As the following graphs indicate, transportation plays a substantial role in the United States’ ever growing demand for petroleum products. It is interesting to point out the relationship, or lack thereof, between vehicle buyer behavior and the price of petroleum within the last year. When considering a policy it is important to recognize additional costs affecting the government (tax payers), manufacturers, and consumers. Recently, the EPA and National Highway Traffic Safety Administration (NHTSA) have made a joint effort to address automobile efficiency and GHG emissions by creating new CAFE standards, we may refer to them as CAFE 2. In contrast with the first CAFE, both LDVs and HDVs are expected to adhere to standards of maintaining a small “footprint” so vehicles of the same size do not compromise safety to achieve fuel efficiency by encouraging the use of light-weight materials while maintaining vehicle size.
It should be noted that all automobile manufacturers do not have to adhere to these standards. A fuel tax can be used in conjunction with efficiency standards or feebates would force drivers to internalize some of the social costs and mitigate the disadvantage of inefficient driving. With government rebates and feebates, the additional initial cost of fuel efficiency is paid by the government and inefficient consumers; some would say the manufacturer as well.
There are many drivers in the construction and use of residential and commercial buildings which impact energy consumption and in turn fossil fuel generated carbon releases into the atmosphere. Electricity is the largest source of energy for buildings, with a smaller contribution made by natural gas, and heating oil. Losses in efficiency are incurred during conversion from one source to another, and from the transportation, and distribution of electricity over power lines. Residential buildings are defined as detached and attached homes apartments and mobile homes.
Growth in housing unit size and demand for energy services has been partially counteracted by improvements and energy intensity. Most of the energy use in a house is devoted to temperature control of space and water, factors which are most influenced by home size and number of occupants. State Energy offices can have an impact on efficiency though standards, incentives and efficiency programs.
Tighter sate building energy codes have been a factor in the rise of residential energy efficiency. Build America is a DOE sponsored research program that focuses on residential building with the goal of accelerating the development of advanced building technologies, reengineering new and existing homes for energy efficiency and affordability. ENERGY STAR focuses on the residential sector seeing a sizeable opportunity to reduce greenhouse gas emissions through improved energy efficiency, with the main objective of working with manufacturers to identifying products which deliver energy savings and environmental benefit.
Presently ENERGY STAR has a market presence of approximately 12% and estimated savings of $200 million annually in utility bills. Offered by Masco Home Services, Environments for Living is a national program which provides a package of services to builders in an attempt to apply the principles of building science to new home construction. Leadership in Energy and Environmental Design is another green building certification system, a third party system of verification which certifies building and community design utilizing strategies for improved energy savings, water savings, and decreased greenhouse gas emissions.
Water and Energy Efficient- Improved efficiency is generally achieved though the use of ENERGY STAR, or otherwise efficient appliances. Material and Resource Quality- LEED discourages the production of waste from and overly wasteful methods of construction, and promotes the use of locally harvested sustainable stock and materials. The average payback period for a Building America home is close to 35 years31, while Environments for living claims a shorter period of 6 to 8 years32.
While the most residential buildings are owner occupied (single family, non-rented), the commercial buildings sector is much more multifarious. The uses of energy in this sector are equally diverse; common uses of energy include space heating, water heating, air conditioning, and lighting, refrigeration, cooking, and running a wide variety of other equipment. The Energy Policy Act of 1992 mandated the Department of Energy (DOE) to support the adoption and enforcement of energy codes in the states. Energy codes specify how buildings must be constructed or perform, and are written in mandatory, enforceable language. Standards are published by national organizations such as the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Energy use in commercial buildings is affected by the adoption of commercial energy codes: States or local governments adopt and enforce energy codes for their jurisdictions, and therefore vary greatly upon location. Additionally, the International Code Council (ICC) is an internationally recognized code development organization. The Commercial Building Initiative (CBI) was launched in August of 2008 by the Department of Energy’s (DOE) Building Technologies Program (BTP) as a government research initiative focused on improving the energy efficiency of new and existing commercial buildings in the United States. LEED Commercial Interiors (CI): for tenant improvement (commercial interiors) projects not involving an entire building.
The dominant commercial uses of energy (all sources) were lighting (21%) and space heating (36%). Lighting is the major consumer of energy in commercial buildings and a target for energy savings through use of energy-efficient light sources along with other advanced lighting technologies. There are many options of lighting available but proving which one is most efficient heavily relies upon a commercial structure’s requirements and goals. The percentage of commercial buildings with lighting was unchanged between 1995 and 2003; however, three lighting types did show change in usage.
CFLs were used in twice the share of lit buildings in 2003 than in 1995, going from 10% to 20% of lit buildings.
Use of incandescent lights was the only lighting type to decline; their use dropped from 59% to just over one-half of lit buildings. In reference to the CBECS lighting usage data, the use of CFL lighting is quite popular and is increasing in usage despite the higher costs relative to incandescent lighting. Furthermore, commercial buildings that invest in CFL lights have a short payback period due to the difference in cost for example, 50k hours, as noted above. Within the last couple of decades the efficiency of HVAC equipment has been a topic of increasing attention. Geothermal heat pumps (GHP) are among the most efficient heating and cooling technologies currently available. Typically, energy recovery ventilation systems can recover about 70%-80% of energy but cost more to install and require more maintenance than other ventilation systems.
Furthermore, ENERGY STAR qualified commercial products can possibly save businesses $1.70 per square foot over the life of the equipment. The Environmental Policy Act of 2005 created the Energy Efficient Commercial Buildings Tax Deduction, a special financial incentive designed to reduce the initial cost of investing in energy efficient building systems via an accelerated tax deduction. Also, The Commercial Buildings Tax Deduction expiration date has been extended twice, most recently by the Energy Independence Act of 2007 (EISA). With such extensive tax incentives, the cost efficiency of implementing newer, more energy efficient technologies in commercial buildings is greatly affected.
Energy is a fundamental component that is found in almost every good and service in the global market. In order to reach energy sustainability, as a society we must take the initiative to strive towards efficiency by focusing on improvements and in the development of new technologies.
To better understand the topic, industrial energy efficiency, it’s important for one to know the basic definitions that are associated with this aspect.
New approaches need to address challenges that are focused on the long-term impact that it will have upon future society. In the Industrial sector of energy there are many different uses and varieties in which energy is used.
The United States Department of Energy has developed a specific program that’s sole purpose is to lead the United States into energy efficiency and productivity. This program assesses available technologies for improving energy efficiency and to encourage those technologies to be more widely used.
ITP gives customers the reassurance that the Department of Energy (DOE) supports and agrees with the new technology performance in industrial applications.
Improving energy efficiency of the industrial sector is expensive and sometimes not guaranteed to work the government has implemented a program that supplies the manufacture or company with initiatives to take that step towards improved energy efficiency. For technology and research stages of industrial efficiency private-public part take in cost sharing partnerships.

According to, more than 70 percent of sockets in America still contain the old, inefficient incandescent light bulbs.
With so many countries phasing out heavy wattage incandescent bulbs, we feel it's time to take a hard look at the energy efficient light bulbs on the market right now. Using light bulbs to save energy is extremely important to our environment and your energy costs. Over the last few years in the European Union incandescent bulbs have been phased out and replaced by compact florescent light bulbs or CFLs. Before we get into the specifics of each light bulb, we would like to clear up some confusion on Lumens and watts. The two cannot truly be compared, but this could help you determine how important each factor is to your energy efficient light bulb needs. In 2008, the Energy Department launched a competition that was designed to kick start the development of energy efficient light bulbs to replace the out-of-date technologies from centuries before.
In 2009, Philips Lighting North America entered its LED bulb in the L Prize 60-watt category, due to the use of roughly 971 million 60-watt incandescent bulbs used a year. The lifespan of a LED lasts over 60,000 hours compared to the 1,000 hours of a traditional incandescent bulb, this saves a lot of energy used to produce and dispose of the bulbs. Between the 1920s and early 1930s, Europeans researchers were testing neon tubes with phosphors, a material that absorbs ultraviolet light turning the light white.
The serious need for energy efficient lighting in American war plants caused a rapid adaptation of fluorescent lights. CFLs can last up to 10 times longer than incandescent bulbs, saving on production and disposal costs. You must carefully dispose of CFLs because they contain a small portion of toxic mercury that does not release while in use but may become a problem if improperly disposed.
These bulbs do not always work so well with dimmers, in fact, you have to buy more expensive bulbs for dimmers.
The fact that CFLs contain a small amount of the highly toxic element mercury is often considered when deciding on an energy efficient light bulb.
Earthmate Mini-Size Bulbs and Litetronics Neolite are the lowest brands with only about 1 mg each.
Turn off anything in your home that moves air, such as, your air conditioner, heater or ceiling fans. Find all the things you need to clean up the bulb, such as, some stiff paper or cardboard, sticky tape, baby wipes or a damp paper towel, and a glass jar with lid or sealing plastic bag.
Carefully scoop up particles with wet paper towel or baby wipe on the piece of stiff paper or cardboard and then deposit into the jar or plastic bag. Check your local government’s website to see if you need to take the contents to the landfill or recycling center.

Although CFLs use mercury directly in their products the energy saving aspect of CFLs will help save the planet from the harmful mercury gas emissions that would take place creating that energy.
Over the past 180 years, many changes have advanced incandescent lighting, which includes changing the traditional filament to a tungsten. Even energy saving halogen light bulbs use a lot more energy than any other popular light bulb on the market. These bulbs only have a lifespan of about 1,000 hours using more energy to produce and dispose of the bulbs. We hope the information we've provided will help you make an educated decision on which energy efficient light bulbs are best for your home. The light bulb size and specifications of the F30T12 lamp are the following (30 watts, T12, 36 in, bi pin), For the F32T8 lamp, it is 32 watts, T8, bi pin and 48 in.
The ISG-IS LED Advantage The advantages of ISG-IS LED Lighting over existing HID lighting technologies will change the way we see and use light.
For use with Exo Terra Halogen Basking Spot (sold separately), as well as other types of halogen bulbs (max. The coating reflects the otherwise wasted light rays and stores the light energy during daytime and slowly releases it at night, which makes this fixture more energy efficient then conventional fixtures. One or more Exo Terra Halogen Glow Lights can be mounted on the rim of the terrarium or aquarium and directed to the basking area with the spring-loaded swivel clamp or it can be put on top of a metal screen cover in any desired location.
The transportation sector consumed 12.9 million barrels of petroleum (71%) in 2009 and 28% of total energy in the United States2. The following graph shows the purchase behavior of cars and light trucks in 2008 when government has already notified the public of new efficiency standards.
By taxing fuel we assume that markets are competitive, social costs are internalized, and the private consumers by themselves will reach an efficient solution7. Congress enacted the Energy Policy and Conservation Act of 1975 which established Corporate Average Fuel Economy (CAFE) regulations in the United States. The three main objectives of CAFE 2 are energy efficiency, fuel efficiency (MPG) and reduction in GHG emissions. By using the footprint method, selling more small vehicles does not help manufacturers meet footprint standards. Many high end companies such as Maserati, Mercedes-Benz, Jaguar, and Porsche have opted to pay fines14. Small conducted an analysis over the combination of these two policies and found results to be more efficient that either policy by itself. However, consumers can still benefit from efficiency without the help from government policies. Drivers which influence building construction include: population, economic growth, building size, energy prices, and the efficiency with which energy service demands are met. Growth in household wealth and other factors have spurred demand for larger homes and more energy services.
Over the past 3 decades, refrigeration, ventilation, insulation, windows and temperature control have become more efficient. Department of Energy is tasked with setting standards for equipment and appliances in order to reach the maximum level of energy efficiency that is technically feasible and economically justified.
Utility companies, working alone or in consort with state energy offices, offer incentives for agency improvements and sponsor efficiency programs targeted at achieving peak load reductions.
More new homes are being constructed to meet the target of energy efficiency programs, and 46% of new home buyers cite energy efficiency as a major consideration in their purchasing decisions. Specific goals include: developing retrofit strategies to improve existing homes, producing new housing with 40% to 100% less energy use, reducing construction time and waste, and improving builder profitability.
It is a method that unites the traditionally independent disciplines of the industry, architects engineers, builders, equipment manufacturers, and materials suppliers etc into teams that assess structures as a whole and use program benchmarks as a standard of comparison.
Environmental Protection Agency created to identify and promote energy-efficient products to reduce green house gas emissions. Easy access is provided to the consumer by hotline and website containing information on 18,000 different products from 1,250 manufacturers. The program is performance based and does not require builders to use a particular manufacturer’s product. Certified Green delivers 20% energy saving 20% water savings, and a 20% reduction in greenhouse emissions. LEED offers the best information on payback periods publishing an average for each certification level, with 3 years for minimum certification, 3 to 5 years for silver, 5 to 10 for gold and 10 and more for platinum certification.33 ENERGY STAR offers an array of spreadsheets to calculate payback period on an apliance by appliance basis. It consists of service-providing facilities and equipment of a wide variety of structure categories such as: offices, hospitals, schools, police stations, places of worship, warehouses, hotels and shopping malls. Furthermore, it is undisputed that every structure has unique and individual energy needs, but the most common sources used to satisfy those needs are electricity and natural gas. Similar to the Residential sector, it is the primary commercial fuels source for space and water heating, cooking, and drying.
Furthermore, The American Recovery and Reinvestment Act of 2009 provided a new goal for DOE's building codes efforts - 90% compliance with energy code requirements for each state. A product of the ICC is the IECC: A subset of international codes and is a model energy code that makes allowances for different climate zones. It is much like the aforementioned Building for America program aimed at residential efficiency. First, CBI is conducts research to dramatically improve the efficiency of existing buildings, in which the key focal point is identifying the most cost-effective retrofitting strategies that also improve the safety and comfort of existing buildings. Green Building Council (USGBC) and provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. Due to lighting systems producing large amounts of heat, energy efficient lighting can also potentially reduce a building’s cooling requirements.
Compact fluorescent lamps (CFLs) and halogen lamps showed a significant increase between 1995 and 2003, while the use of incandescent lights declined. Incandescent lighting has proved to be inefficient in terms of lifespan and watt usage ( 46 more watts used than CFL bulbs). Efficiency of these systems was originally targeted for the associated cost benefits and energy savings to combat rising energy prices.
A couple of benefits of forced air systems, which are now widely applied in churches, schools and high-end residences, are 1) better air conditioned effect 2) up to 15-20% energy saving, and 3) evenly conditioned effect.
GHP’s rely on the stable, even temperatures of the earth to provide heating cooling and water heating. Ventilation works best when combined with methods to avoid heat buildup in your home; but there are technologies that specifically enhance ventilation and energy efficiency, such as an energy recovery ventilation system. A given example of savings: $12,000 dollars in savings when using ENERGY STAR qualified HVAC equipment in a 12,000 square foot building. With this extension, the CBTD can be claimed for qualifying projects completed before January 1, 2014. With increasing energy prices and rising economic concerns that have surfaced it is vital to increase options in alternatives of energy sources. Future developments as well as current ones depend upon efforts to improve industrial efficiency that center around manufacturing and the utilities sector.
Energy Information Administration (Independent Statistics and Analysis) Oklahoma’s leading industries are petroleum and coal products manufacturing, machinery manufacturing, and food manufacturing.
Other energy sources referred in the graph below show 43% of manufactures use of utilities such as heat, power and electricity generation. This drop was not surprising, as the industrial sector was particularly hard hit by the recession. The Industrial Technologies Program’s mission is to transform the method in which the United States industry uses energy by implementing new developments in technology and applying them to existing problems.
It is important to meet criteria of technology claims, and address critical need in the manufacturing sector. The enhancement of credit terms through federal guarantees allow borrowers to obtain better interest rates than using an alternative means of funding such as private lending markets. In sharing research and development costs allows new developing products or cost-savings products enable government agencies (ITP) and companies to achieve a broader policy agenda. We now have a better understanding of how much energy small gestures such as changing your light bulbs can make.
The Ecodesign Regulatory Committee believes this small change will save citizens almost 40 TWh a year, a TWh is equal to 114 million watts.
Lumens need to be considered when the brightness of the room’s light is an important factor to you.
These will include a brief history, pros and cons list, and a chart showing the specifics of each bulb. After two years of intense testing and field assessments the Energy Department announced Philips Lighting North America’s LED would be awarded the first L Prize in 2011.
This creates a more direct and efficient illumination, unlike other bulbs that produce heat and light in every direction, losing as much as 50 percent of the light before it even has a chance to leave the fixture. Other light bulbs create light using heat, which takes a lot more energy than the use of diodes.
During the 19th century, Heinrich Geissler and Julius Plucker, discovered they could make light by extracting the air from a long glass tube and sending an electrical current through it. These lights lasted longer and were three times more energy efficient than traditional incandescent bulbs.
They are smaller, more reasonably priced, save a lot more energy than traditional incandescent bulbs and last longer. On average a typical CFL contains about four milligrams of mercury, but that number can go down to as much as only one milligram depending on the brand and up to five. A handful of companies have dedicated themselves to the pursuit of using the least amount of mercury possible. Remain calm, it can take anywhere from hours to days for most of the mercury to seep out into the air.
The device is sturdily constructed, with a metal reflector, heat resistant ceramic socket, and a spring-loaded swivel clamp. Recent concerns regarding depleting petroleum supplies and adverse environmental effects of greenhouse gases have triggered interests in automobile efficiency by governments and consumers, alike. This data challenges the general assumption under a free market approach that consumers will choose more efficient vehicles if presented with higher prices.
Smaller vehicle size in Europe and other countries relative to the United States is apparent.
CAFE regulations provide a quantitative target and provide the base for fuel efficiency standards in the United States.
The new changes will include standards for Heavy Duty Vehicles and amendments to existing standards for Light Duty Vehicles (LDVs). It is important to note the incentive for lighter vehicles on the grounds of safety concerns. Consumers internalize the cost of additional fuel intensity (the reciprocal of fuel efficiency) by paying a higher price.
The present discount period value and payback period are essential in determining when the buyer will receive benefit rather than loss from the additional cost spent on their initial investment to receive efficiency. Services demanded of buildings which require significant energy use include: lighting, temperature control, water heating, as well as tasks specific to the domestic and work environments such as cooking, refrigeration, computing and electronic entertainment. Meanwhile both residential and commercial energy use is growing accounting for, in turn, a growing share of energy consumption.
Increasing energy consumption per household and increased saturation of appliances and equipment such as computer and entertainment systems has resulted in larger demand for energy, in particular electricity. A slow trend in consolidation (larger firms are buying out smaller firms) has resulted in the top 5 builders in the country accounting for over 20 % of the closings on new homes. The department attempts to establish standards that maximize consumer benefits and minimize negative impacts on manufacturers and other stake holders.
According to the DOE it is possible to design and construct new houses that are 30% to 40% lower in energy intensity than the typical house, at little additional cost. Typically the process involved consists of first designing, building, testing redesigning retesting and retrofitting spec houses employing system performance analysis using program specific benchmarks. Additionally the program provides technical information and tools that organizations and consumers can use to choose energy-efficient solutions and best management practices.
Rather, strict requirements for construction ventilation, improved thermal systems, air pressure balance, internal moisture management combustion safety must be met before certification can be attained. Office buildings, the most common type of commercial building, account for 17 % of buildings, floor space, and energy consumed. The Commercial Building Energy Consumption Survey (CBECS) noted in 2003 that electricity and natural gas account for more than 87% or 6500 trillion Btu of the total energy consumed in the commercial building sector.

Projected growth rates of such sheer magnitude would seemingly directly correlate to increased demand for energy, but over the years the amount of commercial floor space has at times outpaced the increase in demand; therefore, the intensity of total energy use in decline. However, a separate set of codes and standards apply to buildings constructed or used by any Federal agency. Second, CBI is developing strategies to construct new, marketable buildings that achieve 50% to 70% whole building energy improvements, relative to ASHRAE Standard 90.1-2004. It accomplishes this through a third-party verification system and is internationally recognized.
Department of Energy helping us all save money and protect the environment through energy efficient products and practices.
More currently, increased awareness of environmental issues and better technologies have led to more concentrated efficiency efforts.
A drawback is the installation cost, which might be slightly higher than traditional HVAC system.
This type of system provides a controlled way of ventilating a home by using a heat exchanger : They heat ventilated air in the winter by transferring heat from the warm inside air being exhausted to the fresh (but cold) supply air. However, these systems are most cost-effective in extreme seasonal climates and where fuel costs are high.
In the United States market, the industrial sector is a large fraction of consumption of energy.
The concept of energy efficiency in the industry sector faces many obstacles that prevent potential progress in the development of energy efficient programs. Also included in the “Other Sources” category are wood residues from mill processing, steam, pulp from liquor from making paper, agricultural waste, and wood-related paper-related refuse. This government program also supports those developments and research by sharing in the costs. Administration of federal grants and direct loans in reducing early capital costs are available to some approved companies and organizations.
Small, Energy Policies for Automobile Transportation: A Comparison using the National Energy Modeling System.
See the infographic below to learn how a small change like switching to energy efficient light bulbs can mean to our environment and your wallet. Remember these numbers the next time someone says replacing your bulbs will not save much energy.
This burst open the door for LEDs to begin being mass produced and widely considered the future of lighting. The residential bulb was created by making a spiral shape, this was the first Compact Fluorescent bulb or CFL.
In more recent years, due to mass bans of incandescent light bulbs in many countries, incandescent bulbs are being improved and becoming more energy efficient, specifically with their Halogen light bulbs model.
Over the last 50 plus years General Electric has made big strides in improving the efficiency of Halogen bulbs.
Although some energy efficient light bulbs may initially be more expensive, they prove to pay off big time in the long run. In this aspect we are the greatest contributor to issues such as depleting resources and environmental degradation which have global effects. It is also possible that consumers will only react to severely high prices maintained for a relatively long period of time. This could be attributed in large part to much higher fuel taxes which cause consumers to internalize the social costs by paying a higher price. They apply to passenger cars, LDVs, and medium-duty vehicles and will require an estimated average emissions level of 250 grams of carbon dioxide per mile by year 2016. Some technological advancements are necessary to reach efficiency standards while maintain current safety rating. This is essentially the idea of a feebate, however, with the feebate method consumers are charged for their inefficient behavior and the money is used to provide other consumers with rebates for efficient vehicles.
This issue becomes specifically important for consumers considering alternative fuel vehicles. Further, in 2008 the DOE released a schedule for setting new appliance efficiency standards, and a plan to address a rule making backlog in order to meet the requirements of the Energy Policy and Conservation act, as modified by the Energy policy act of 2005. Electricity on the other hand, accounts for 55% of sources of commercial end use energy consumption, which is 3.5 quadrillion Btu.
In relation to the commercial buildings market, LEED provides a variety of distinct tools relating to building retrofitting and new construction. In the summer, the inside air cools the warmer supply air to reduce ventilation cooling costs. Addressing changes and welcoming innovation in technology in this market will lower the United States consumption thus making it more efficient. Better use of technology that requires less energy to perform the same tasks and functions will enhance energy efficiency. Once those concerns are met they can begin to take existing technologies to see how to improve industrial energy efficiency.
These government loans are not required to be paid back which decreases capital costs tremendously. It was not until the beginning of the 20th century that these lights started to gain traction as neon lights and other outdoor lighting. Since the machinery to mass produce these energy efficient light bulbs cost so much money the early prices were relatively high between $25-35, but varied based on different utility company promotions.
All around the same time as Edison the less famous William Sawyer and Albon Man also received patents for the incandescent lamp and Joseph Swan patented a light bulb in England.
While they are still not on par with CFLs or LEDs energy savings, they are still helping save more energy than traditional bulbs.
The inside of the reflector is coated with a highly reflective luminous coating that continues to glow long after the lamp is turned off. As a developed leader in the world’s economy it is imperative to adhere to the highest standards of transportation efficiency. European drivers are much more likely to choose a diesel fueled vehicle as a result of relatively lower diesel taxes. Fuel efficiency standards gradually rose until about the mid 1980’s, at this time automakers had met standards for Light Duty Vehicles (LDVs) and the price of liquid fuels dropped dramatically. However, larger vehicles are only safer for its occupant not for anyone colliding with it12.
An efficiency target is established, similar to the CAFE regulation, and is reached by those who chose to the purchase of more efficient vehicles. General insurance policies charge the fixed amount regardless of quantity of time spent driving. The basic definition of a payback period is the amount of time it takes to regain your initial investment.
Together both commercial and residential sectors account for more than 40% on of total U.S. Commercial Buildings, their energy related characteristics, and their energy consumption and expenditures. Improving industrial energy efficiency will lead to a reduction in national energy consumption. Boiler fuel is the process in which in producing heat that is transferred to the boiler vessel to generate steam or hot water. The federal government offers grants to cover partial or total cost of feasibility studies, demonstrations, or the purchase of new technologies. Today, Westinghouse light bulbs offer a large variety of LEDs and other energy efficient light bulbs. The public shied away from buying the CFL bulbs because these high prices and the big bulky look of the bulbs. The light bulb began its journey around 1835 when scientists realized you could create a constant stream of light. This allows diurnal reptiles and amphibians to retreat in their night burrow or hiding without stress.
Motor gasoline, the primary fuel for passenger vehicles, has been responsible for approximately 60% of U.S. High prices provide a disincentive for fuel consumption, reducing excessive acceleration, speeding, and overall vehicles miles driven (VMT), and in turn reduces emissions.
In fact the overall risk (including risk to others) is generally higher with larger vehicles. In a NEMS-RFF study by Kenneth Small, feebates created greater efficiency gains though the use of hybrid and diesel than the CASE standard but it also provides incentive for greater VMD. In terms of economics, this means that the person who drives more often and greater distances, the freerider, is benefiting from those who drive less frequently and fewer miles. In the case of efficient vehicles it would be the additional cost incurred by buying a vehicle that runs off of alternative fuel rather than a conventional vehicle divided by the amount saved on fuel per year. The burning of fuels to supply buildings with electricity makes buildings responsible for the largest share of U.S. Cost effectiveness is the primary struggle in implementing energy efficient technologies for larger corporations.
A moon-like glow enables nocturnal reptiles and amphibians to see properly without disturbing their night cycle. A debate arises between those who believe components such as price and competition will create equilibrium in the market resulting in efficient energy use and those who insist government intervention is imperative to incentivize efficient behavior, thereby, avoiding complete resource depletion and hazardous environmental repercussions. Infrastructure costs for implementing the policy are low and require little capital investment. As a result, consumer preference for larger, heavier, less fuel efficient vehicles began to increase.
Another main disadvantage is that the policy gives the user no incentive to use other means of reducing fuel consumption, such as limiting excessive acceleration and reducing total vehicle miles drive (VMD). A usage based insurance policy would internalize the social costs of driving and change overall consumer habits. Factors to determine the amount saved include: the difference between the new technology and conventional technology, price differences among fuels, and vehicle fuel efficiencies, and annual distance traveled. It is also ideal to monitor your animals during night time, without switching on the lights which can cause stress and disorientation.
Despite these benefits, fuel taxes are unpopular among consumer because they dislike paying higher prices. The following graph demonstrates this change, showing a general shift in ownership from automobiles to trucks.
In fact, there is greater incentive for consumers to drive these vehicles because they pay less per mile. Some key elements that can cause the actual payback period to vary from the predicted are types of usage (highway vs. Obstacles that restrain operators from making changes are cost of downtown to implement new system, costs of capital, and retraining time. Many economists oppose the idea as well because raising prices can cause an economic deadweight loss, however, much of this can be mitigated is revenues are returned to consumers by reducing taxes. However, as energy rates rise those technologies will become more appealing as they become cost effective, ensuring the benefit will out weight the cost. However, the most importantly, the payback period does not take into consideration the time value of money (present discounted value). The cost benefit will depend on the performance, reliability of the equipment and the incentives of switching to something new.
When calculating a cost benefit analysis it is crucial to take into account that your money is worth more in the future. Otherwise, if a consumer reads that the payback period for a hyrbid is 5 years of a CNG vehicle is 8 years without considering the time value of time they underestimates the true economic benefits of their investment.
The illustration below shows very clearly how the various technologies compare, the results are more light with even less energy. Use the ISG calculator to work out how much money you will have by upgrading to LED technology.
You will notice its a significant amount of money especially when you look at the LED calculator with multiple luminaires.
