Long ago, the energy we used to do things like heat and cook came from locally sourced firewood.
That leaves about 6 billion people, most of whom probably rely on electricity virtually every minute of every day. Compared to the world breakdown of fuels, we’re not that far off, except that hydropower comprises a greater proportion of global electricity production (15.8%) than it does in the US (just a few percent).
The steam travels through boiler pipes where the pressure and speed turns the blades of a turbine. Nuclear power is a mystery to many people, but in simplest terms, nuclear electricity generation is just another way to boil water. It is worth noting that a technology called solar thermal electric generation has begun to have an impact on US markets in the past few years.
Humans have been using the sun, water and wind as energy sources since the beginning of time, yet they comprise what we call alternative energy. The immense natural power of water can be used to turn a turbine through a variety of methods including channeling through dams, submerging the turbine in an area with predictable tides, using the pressure created by ocean waves, and even small turbines submerged in minimally disturbed rivers and waterfalls.
Wind power continues to be a rapidly growing source of renewable energy throughout the world. Photovoltaic cells, what most of us think of as solar power, are unique in that there is no steam or turbine. The energy mix that powers your home with electricity depends on where you live and your utility company.

EIA's Energy in Brief: How much of the world's electricity supply is generated from wind and who are the leading generators? Home > Energy in Brief > How much of the world's electricity supply is generated from wind and who are the leading generators? Worldwide wind power generation exceeded 250 billion kilowatthours in 2009, which is equivalent to the annual electricity consumption of over 22 million average households in the United States.
A feed-in tariff is a financial incentive that encourages the adoption of renewable electricity.
Maintaining its position for two years in a row, the United States led all other countries in wind power generation in 2009. According to the World and European Wind Energy Associations, installed global wind capacity reached 197,000 megawatts by the end of 2010, with just over 3,000 MW of that total located offshore.
Over the lifetime of the plant, electricity from wind power generally costs more than electricity from power plants burning fossil fuels.1 However, wind power is expected to continue to grow worldwide because of favorable government policies. Although wind farms have relatively low operating costs, capital investment costs are significant. Every week, for the sixth season of Game of Thrones, Christopher Orr, Spencer Kornhaber, and Lenika Cruz will be discussing new episodes of the HBO drama. When his three children were young, Warren Buffett installed a dime slot machine on the third floor of the family’s house, in Omaha, Nebraska.

From joy and attachment to anxiety and protectiveness, mothering behavior begins with biochemical reactions.
The artist Sarah Walker once told me that becoming a mother is like discovering the existence of a strange new room in the house where you already live. Because a lot of things do change, of course, but for new mothers, some of the starkest differences are also the most intimate ones—the emotional changes.
Even before a woman gives birth, pregnancy tinkers with the very structure of her brain, several neurologists told me. That race will be much shorter—a 73-day sprint to hand over control of the entire federal government from one administration to the next. For the last eight years, a collection of ex-government officials, good-governance advocates, and lawmakers in Congress have been working to improve presidential transitions.
The Republicans are now going the way of the Whigs—by embracing the politics that helped destroy them.
One hundred and sixty years after the founding of the Republican Party, Donald Trump has evoked Abraham Lincoln as a standard for his branding.
Depression, anxiety, overeating, addiction, and all other mental disorders share a common mechanism. The need for an alternative source of energy for mankind was never as important as it is today.
Solar energy works on a simple concept – the sunlight is captured, converted solar energy and distributed power. That there may be some environmental benefit in Hydrogen Fuel Cell Vehicles (tackling green house gas emissions) regardless of the use of natural gas.
That the short term use of natural gas to produce hydrogen may be a bridge to the emergence of economically viable renewable hydrogen production to displace natural gas long term. That hydrogen for fuel cells in transportation is a relatively benign and economically constructive use of US natural gas that serves the interests of US energy independence from foreign oil.
If you have not yet been exposed to authoritative-looking green marketing for hydrogen and fuel cell vehicles, you will be. There are no such environmental benefits attributable to hydrogen either now or in any foreseeable future economic reality. Hydrogen Fuel Cell Vehicles are marketed as green to environmentalists and policy makers by comparison to a 23 mpg gasoline vehicle.
The following chart therefore references the 23 mpg EPA Lexus and compares it to variety of modern technology choices from Fuel Cell Vehicles, Diesel, Gasoline and Gasoline-Hybrids to Plug-in Hybrids and pure Battery Electric Vehicles. A Closer Look at Directly Comparable Vehicle Technologies without the reference to either the arbitrary US fleet average or very old or very high power vehicle technologies.
Fact: The EPA tested 2014 134hp Toyota Prius Gasoline Hybrid offers a 60% GHG WTW emissions reduction verses the Average Fuel Cell Vehicle tested by the definitive DOE NREL long term study.
The heavy conversion loss from electricity to chemical fuels drastically impacts the distance that can be travelled per unit of energy depending on source. This is everything the reader needs to know about why the fossil fuel and auto industries are pushing so hard for hydrogen despite, no in fact because it makes no environmental sense.
It is important for any person concerned with environmental protection or simply wishing to avoid being mislead as a consumer, an investor, an editor or a public servant, to be mindful of well funded and extremely widespread misuse of publicly available data regarding Hydrogen production and Hydrogen Fuel Cell Vehicles. Hydrogen represents the limit of fossil fuel refining which results in the maximum hidden well to tank emissions of any fossil fuel and the maximum overall GHG emissions per unit of useful energy. In California, the CARB ZEV mandate permits fossil fuel vehicles (if the fossil fuel is hydrogen) to qualify instead of EVs while the copious green house gas emissions to produce hydrogen for them are released in California just down the road at Air Products Inc., or at the gas station instead of on the street. This document contains minimal interpretation (the data is derived wherever available directly from official EPA and NREL records). The data demonstrates that unless a consumer wishes to purchase a low performance vehicle to replace a very old, a very large or very a high performance vehicle, Hydrogen FCVs offer no net Green House Gas reductions versus any other low performance vehicle.
Unlike the optimal economic synergy of plug-in EVs and Renewables, the economics of hydrogen strongly prevents renewables from competing to power an FCV fleet either now or in the future.
Hydrogen from Natural Gas is currently posing a considerable threat in terms of diverting State and Federal budgets ostensibly intended for environmental improvement to fossil fuel based hydrogen infrastructure where at best very large amounts of public funds are at risk of going to waste assuming consumers do reject low-performance FCVs. Hydrogen Fuel Cell Vehicles and their infrastructure are a case in which the cost to the many should perhaps be considered to outweigh the benefit to the few. Naturally there is unlikely to be a market for Fuel Cell Vehicles outside the demographic of environmentally conscious consumers targeted and duped by false advertising. Of course the most decisive action environmentally concerned consumers can and must take in order to prevent the displacement of solar and wind energy in transportation by fracked natural gas is simply to refuse to lease or to buy a Fuel Cell Vehicle regardless of incentives or public funds wasted on hydrogen infrastructure. Naturally it would be preferable for CARB to anticipate such a response and to resume the role of forcing the focus of auto makers in the direction of more constructive instead of destructive approaches to the environment. For details of public participation and input into California Energy Commission programs including the Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP) Investment Plan, a contact is Alana Mathews, Public Advisor, at 916-654-4489. To dig deeper or if the reader is technically minded and inclined to double check the logic, there are some open source details of the calculations and accompanying notes and references that resulted in the information above. For those unfamiliar with hydrogen production, here is a highly recommended brief and accessible click-through animation. This number takes into consideration only actual CO2 gas and EPA estimated CH4 emissions and EPA estimated GHG potency of CH4. Note also, this is a best case figure from large-scale industrial SMR (steam methane reforming) which benefits from efficiencies of scale.
As an authoritative external frame of reference this is the NREL well to wheel calculation.
Well To Wheel Gasoline emissions are 11.132 Kg CO2 for the production and burning of 1 Gallon of Gasoline. For electric equivalence to produce the same 11.132Kg CO2 as a gallon of gasoline there are published figures available for CO2 per KWh. Now we can take a hard look at a sample of similarly performing vehicles including Fuel Cell Vehicle and also look at both similar and very much more powerful PHEVs and EVs.
While direct compatibility with renewable electricity strongly favors a continuing trend towards an emissions-free transportation in the case of Electric Vehicles, chemical energy for transportation, hydrogen included, inevitably favors the economics of chemical feedstocks.
Some calculations to illustrate the economic specifics of FCV vs EV energy costs via renewable vs fossil fuel pathways.
From these figures it is possible to calculate fundamental cost per mile economic break-even in either direction in three different hypothetical scenarios comparing a 100KW Chevy Spark EV to a 90KW 2015 Toyota FCV. If EVs and FCVs co-exist in transportation allowing FCVs to take least-cost route (natural gas).


We are within three to six years of it being cheaper to run an EV fleet on utility scale solar than it is to power an EV fleet via natural gas. The cost of hydrogen infrastructure must be free of charge to the fossil fuel industry (paid for by public funds).
There must be no accounting for the cost of CO2 sequestration during the production of hydrogen – instead there must be a carte blanche license to pollute. These choices are of course within the remit of the California Energy Commission and similar bodies Nation wide and World wide at this moment. Ultimately, the defining advantage for hydrogen produced by natural gas for Fuel Cell Vehicles is the ability to pollute while claiming to be green.

Julian Cox has had career-long vocation focussed on the positive convergence of economics, energy, transportation and care for the environment. Interestingly, during the 1910’s the electric car (or the 1917 Woods-dual power hybrid) lost to the petrolcar due to radius, cost, availability of fuel, speed of energy intake as soon as the combination of electric starter and improved reliability made the petrol car as easy to drive as the electric one.
The California mandate is contained in the California Health and Safety Code, Section 43869(a)(1)(B) (which applies now to any station receiving state support and they all do) and (a)(2)(B) (which kicks in after 3500 metric tons of hydrogen is dispensed in a given year (approximately 15,000 vehicles), and applies across the board). The studies I cited all assume SMR only as a worst case as well as the California mandate which reflects the current reality.
Yes, I agree that hydrogen is not currently cost competitive, particularly because of the current oil price depression. You may not have full access to the site, some of it's functionality or it may not appear as it was intended. With some data yet to come in, estimates by the International Atomic Energy Agency see nuclear power last year meeting 13-14% of the world's electricity demand, which continues to increase rapidly in the developing world.
One factor in nuclear power's perfomance since 2007 has been the prolonged shutdown of large reactors at Kashiwazaki Kariwa in Japan following the Niigata-Chuetsu-Oki earthquake. The two oldest reactors at Japan's Hamaoka plant that had been out of action for several years were officially retired after a decision to replace them rather than upgrade to meet heightened earthquake resistance requirements.
So far in 2010 Rajasthan 6 has added a further 202 MWe and this year should see seven new reactors totalling 5824 MWe start up. The public information mission of World Nuclear News is supported and made possible by the members of the World Nuclear Association. This doesn’t mean there are a billion people without a source of energy – it’s just not in the form of electricity.
I recently asked a random assortment of ten people to explain how electricity is generated. Together, we required the production of over 22,000 terawatt hours (TWh) of electricity in 2011. In 2011, more than half of our electricity came from coal (42%) and natural gas (25%) combustion combined. Fuels like coal, natural gas, oil and even biomass (like wood and animal waste) are burned in large furnaces.
That mechanical energy is converted into electrical energy inside the generator because of the relative rotation between magnets and an electrical conductor.
Clustered in the US Southwest, these facilities use various methods to focus the sun’s energy to boil water which generates electricity as described above.
To generate electricity, wind and water turn the turbine directly, skipping the energy-losing step of boiling water, and the rest of the process is the same. Hydropower is not without problems but continues to comprise a large portion of the renewable energy sector. Detailed wind maps are constructed to find locations with adequate non turbulent wind without too many powerful bursts. The United States led the world in geothermal electricity generation last year, providing us with four times as much electricity as solar based methods. For instance, power companies serving California, Oregon and Washington generate more of their electricity using hydropower than any other single source. I would like to suggest that some time be spent on the need to generate power in real time-matching supply and demand constantly. Although this article was intended to be a simple primer on electricity generation, you are right that it would be useful to address the concepts of peak demand and other factors that require use of the operating and supplemental reserves. The owners of EnergyEarth make no representations as to the accuracy or completeness of any information on this site or found by following any link on this site. Wind generation increased by about 20% from 2008 to 2009, and has more than tripled since 2004.
Under a feed-in tariff, government legislation requires electric utilities to purchase renewable electricity at a higher price than the wholesale price. The remaining top-ten wind power generators, listed in descending order, were Germany, Spain, China, India, the United Kingdom, France, Portugal, Denmark, and Italy. The next highest levels of wind penetration are found in Portugal at 16%, Spain at 13%, Ireland at 11%, and Germany at 7%. Even though offshore development lags behind onshore, generally due to higher costs and technology constraints, over 1,000 MW were built in 2010. Multiple types of government support exist, including a production tax credit and State renewable electricity portfolio standards in the United States, a feed-in tariff (see the "Did You Know" box on the left) in Germany, and wind capacity targets in China. In addition, the intermittent nature of wind results in relatively low capacity factors, such that a wind plant will generate less electricity than a conventional thermal or hydroelectric plant of the same size and over the same period of time.
Because no screeners are being made available to critics in advance this year, we'll be posting our thoughts in installments. Buffett has spent most of his life as a farmer, with little financial support from his father—until recently.
The objective was to convey the dangers of gambling, but it also meant the children’s allowance remained in his hands. I always liked Walker's description because it's more precise than the shorthand most people use for life with a newborn: Everything changes. After centuries of observing behavioral changes in new mothers, scientists are only recently beginning to definitively link the way a woman acts with what's happening in her prefrontal cortex, midbrain, parietal lobes, and elsewhere. One of the sleights of hand used in generating false comparisons is to include an exaggerated figure for carbon footprint of making propulsion batteries derived from an out-dated (2006) Argonne National Labs report.
95% of US production is from natural gas, most of the remainder from the gasification of coal and it will not change for the better. However as a society we do not use renewable energy to chemically re-assemble gasoline from the exhaust fumes of gasoline vehicles (nor would we even if we had a convenient and abundant resource of concentrated fumes). The least cost pathway per mile for FCVs is so pronounced in favor of natural gas versus electricity from any source as to guarantee steam reforming trumps electrolysis, without CO2 sequestering and with no reason for the natural gas industry to fear cost per mile competition from renewables.
Misrepresentation exists across vested interests and government agencies to paint a picture of this technology as an asset to global efforts to reduce green house gas emissions.
It is therefore urgent from an environmental perspective that confusion on this topic is brought rapidly to a full stop. It is intended to provide a clear and directly accessible view of that data to serve a public right to know it (and to understand it) unmasked from false comparisons and pseudo-science and from political or marketing spin intent on forcing natural gas into the green energy economy. This best case is not even the typical case owing to difficulties in transporting hydrogen in bulk. At worst public funds will embolden the Natural Gas industry and Auto Industry to press for far-reaching delays in EV developments and even lobby for effectively the society-wide derailment of progress towards renewable energy in transportation. In that regard I trust this document comes to the defence of the widest possible audience as it contains vital consumer education. According to the NREL long term fuel cell vehicle study on-site production (at the refueling station) is often deployed. 23*484 = 11,132g We can cross check this figure with a DOE study which shows 450g CO2 per mile for a 25mpg gasoline vehicle. According to H2USA ‘Recent development of the United States’ tremendous shale gas resources [is] helping to reduce the costs of producing hydrogen and operating hydrogen fuel cells’. But with an artificially imposed societal choice of FCVs, that goal is at risk of being pushed out by approximately 12 years of additional entrenchment in a fossil fuel transportation economy. Amortizing that cost and risk of consumer rejection of FCV technology is never accounted for in the cost of Hydrogen. It is not good enough that images of celebrities drinking distilled exhaust emissions sets the standard of public education on such a pivotal societal choice.
Electric cars may lose again, probably to liquid energy user, or some (systemic) innovation will replace the private car altogether (which would remind us of the motor car solving the huge menure-problem all big cities were facing around 1900.
I agree that FCEVs using SMR sourced H2 is not as clean as a comparable BEV, but contrary to the conclusion of the article, it is not dirtier than a comparable ICE vehicle. This, the largest nuclear power plant in the world, accounts for 2% of nuclear capacity and was completely out of action for many months. Closures included France's Phenix, a prototype fast reactor which produced 233 MWe, and Lithuania's Ignalina 2 which produced 1185 MWe but has been closed early as a condition of EU entry.
It was hard work to chop and haul that energy source, so folks probably didn’t keep putting wood on the fire when they didn’t need the heat.
Those without access, and some with limited access, still rely solely on solid fuels like coal and wood for heating and cooking.
Especially in the US, the contribution of natural gas is on the rise, bucking the predicted price increase and remaining competitive with coal. After that, it is the same as burning fossil fuels: the heat boils water, the water turns to steam and steam turns a turbine which is attached to a generator.


Though this technology still occupies a very small share of the market, a recent report by the US Energy Information Administration reports that several new large installations are about to double the electricity generating capacity of this method. Installations can be found on mountain ridges, plains, coastlines, and in coastal ocean waters.
These plants use the steam that is produced from heat that occurs naturally a few miles beneath the Earth’s surface in some places.
Since we tried to keep this post brief, we also knowingly omitted discussions of energy storage and transmission as critical in the development of renewables. The owners will not be liable for any errors or omissions in this information nor for the availability of this information. This growth is mostly due to capacity increases in the United States, China, India, and Western Europe. This incentive allows the renewable generator to achieve a positive return on its investment despite the higher costs associated with these resources. Although about 35 countries reported significant wind power generation in 2009, these top-ten countries accounted for more than 85% of all wind generation worldwide. No other country surpassed 5% penetration, including the United States, which generated almost 2% of its electricity from wind in 2009. Western Europe is home to nearly all existing offshore capacity; Japan and China have started to add offshore wind farms of their own. The United States prides itself on a tradition of a peaceful transfer of power from one administration to the next, no matter the political party.
Nevertheless Hydrogen Fuel Cell Vehicles are without equal when it comes to misdirection and as a tool for extracting public funds from officials only too ready to be blind-sided by pseudo-science and the lobbying of vested interests in a nation struggling to triage the cost of foreign oil and consumer environmental concerns while newly awash with abundant cheap Natural Gas from hydraulic fracturing of shales. A 23 mpg is also a ‘GREET 1b’ definition of a ‘mid sized family car [of average age of fleet]’. The green bars are emissions reduction and purple is performance reduction vs the 23 mpg gasoline vehicle. EV batteries on any significant scale are now known to be produced and planned for production without a significant carbon footprint and with very considerable cycle life, second use in storage and end of life recyclability. It is for exactly the same reason that we will not as a society electrolyze H2o (the exhaust of fuel cells) even though abundant water is often available.
Accordingly should FCVs be adopted, natural gas will prevail economically long into the future, and long after the date by which EVs could be operated economically on 100% clean renewables on a large scale to the exclusion of fossil fuels.
Mistaking fossil hydrogen from the hydraulic fracturing of shales for an environmentally sustainable energy pathway threatens to encourage energy policies that will dilute and potentially derail global efforts to head-off climate change due to the risk of diverting investment and focus from vehicle technologies that are economically compatible with renewable energy. There is no reason to imagine that a future 306hp FCV will not pollute far more than the current 306hp gasoline V6 Lexus when the average FCV tested by NREL already produces 73.5% of the emissions with less than half of the power.
Replacing an EV, PHEV, HEV (or even a small-engined diesel or gasoline vehicle) with this FCV will represent an environmental set-back. Hence the on-site (distributed) production from natural gas at fueling stations that suffers lowered efficiencies of scale. 90% of the Californian Energy Commission hydrogen infrastructure budget has been earmarked for non-sequestered fossil fuel production of Hydrogen in return for lip service of future environmental benefits that can never be forthcoming.
Figures originating at Argonne National Laboratory and republished in graphical form by hydrogen fuel cell lobby group Californian Fuel Cell Partnership arrive at 62% efficiency inclusive of transportation. Ford, a participant in the NREL study refers to it as distributed natural gas steam reforming. This is a 100KW (134hp) EV, which provides direct comparison with typically 100KW (134hp) FCVs. Methane from natural gas contains the energy potential for self-disassembly into Hydrogen and CO2 via the process of steam methane reforming and as a result it is the simplest, cheapest and most economically unassailable source of hydrogen, that is best equipped to see off meaningful competition from electrolysis, biofuels and waste-stream reformation – so long as vehicles are chemically and not electrically powered. This is a potential disaster for renewable energy in transportation and for the environment that PON-13-607 and initiatives like it encourage at the public expense assuming consumers cooperate in the purchase of FCVs. Eg going to wintersport areas from the Netherlands or Northern Germany takes a 800-1000 km drive (and the same back). This was the last of the EU-motivated shutdowns that have taken away a total of 4806 MWe since 2002. The two new reactors of 2009 were Tomari 3 in Japan and Rajasthan 5 in India, both connected to the grid in December so were too late to affect 2009 figures. Now that obtaining energy in the form of electricity is as easy as flipping a switch, we don’t have much reason to think about where it comes from and how it’s made. All but two of them hadn’t the faintest idea how burning coal, nuclear reactions or spinning wind turbines leads to the electricity that powers our lives. As consumers we don’t have much control over our electricity sources, but Amory Lovins, physicist and energy expert, called energy efficiency the world’s biggest untapped energy resource.
I would also suggest that in order to increase renewables, you need storage because renewable generation does not match demand. The owner will not be liable for any losses, injuries, or damages from the display or use of this information. Despite this growth, the world still generated only 1% of its total electricity from wind power in 2009. As of June 2011, there were no operating offshore wind farms in the United States, although the Department of the Interior approved construction plans for the 420-megawatt Cape Wind project off the Massachusetts coast in April 2011.
The answer: 47 percent of respondents said that either they would cover the expense by borrowing or selling something, or they would not be able to come up with the $400 at all.
It is just that the false promise of hydrogen is such a dangerous deception in environmental terms that it cannot be allowed to go undetected at the eleventh hour for the environment and on the eve of genuine progress with simultaneous break throughs in solar energy costs and Electric Vehicles capable of addressing the mid market. Negative performance reduction denotes performance increase compared to the 23 mpg vehicle. The energy efficiency barrier is too high and electricity is too valuable to waste on essentially the un-burning the oxidation products of other fuels. Hydrogen is locked by the force of economics to natural gas and natural gas is increasingly locked by the same force to the practice of on-shore hydraulic fracturing of shales.
Toyota for example, currently the world’s largest auto maker is the most active supporter of lobby groups in the US and world-wide in pushing for hydrogen while it has tragically sidelined its own efforts to produce EVs.
This is a fact that cannot have escaped either Mercedes (Daimler) and Hyundai-Kia who were both NREL test subjects alongside Ford and GM, BP, Shell and Chevron. The real-world data attests to the fact that when installed in a hybrid electric vehicle the real-world energy conversion efficiency is insufficient to overcome the added GHG emission intensity of hydrogen production. Meanwhile marketers of FCVs actively and openly target Electric Vehicles (not gasoline or diesel vehicles) with claims of convenient access to lowered green house gas emissions similar to a pure Electric Vehicle. The answer is 1.49 US Cents per KWh to be competitive with natural gas or more than double the cost reduction to be competitive in an EV system. One of the reasons that electricity remains such a mystery is that we don’t need to think about it. For perspective, it would take just 1 TWh of electricity to light 10 billion 100W light bulbs for an hour. Interestingly, December 10th marked the end of a 20 year program called “Megatons to Megawatts” whereby the United States purchased the uranium from 20,000 retired Russian warheads and processed it for use in power plants.
Just last month amidst great controversy, the Federal Register published a decision designed to promote the development of wind power but may lead to an increase in the deaths of golden and bald eagles.
Materials that do not exhibit this photovoltaic effect just absorb the photons and heat up when struck by sunlight.
By using less energy to perform the same task, we are not sacrificing comfort or convenience, simply using less electricity. Wind generation growth in the country increased by an average of 80% each year since 2004 and doubled from 2008 to 2009. On the most basic level, these changes, prompted by a flood of hormones during pregnancy and in the postpartum period, help attract a new mother to her baby. The Y axis gives the correct number for all bars be it a percentage or a number in MPGp (miles per gasoline gallon equivalent well to wheel pollution) or vehicle power in bhp.
Natural gas is a cheap and abundant resource that comes out of the ground with energy potential for self-disassembly into hydrogen and CO2. Hence on any meaningful scale the production of hydrogen from water cannot ever compete in the open market with an abundance of energetic fuels direct from the ground. Hydrogen is the Hydro in fossil HydroCarbons and hence hydrogen cannot be extracted from the ground without simultaneously extracting and disposing of carbon as CO2. Of this group, only Ford, to their credit, has publicly stated that there is no significant environmental benefit to Fuel Cell Vehicle Technology – all be it at the bottom of a web page discussing the merits of tackling climate change.
Technological advancements in semiconductor materials that can be applied in thin layers and still efficiently turn photons into electricity are progressing so rapidly that the IEA predicts photovoltaics will grow more than 11.5% a year through 2040.
There is no example of a 23 mpg Toyota branded sedan, for example the 3.5 liter Toyota Camry only gets 268 hp and as a result has an EPA combined gas milage figure of 25 mpg. Steam methane reforming is economically unassailable as a method of hydrogen production by clean but more complex methods. The larger the scale, the greater the percentage of fossil fuel use in the production of hydrogen. Re-Capturing the carbon (sequestering CO2) costs about the same as the resulting hydrogen fuel and hence it is simply released to the atmosphere.
Even though we’ve received our last shipment, the uranium from those warheads will be providing Americans with electricity even after 2020.
