The bloggers in this article suggest that one of the biggest selling points for electric cars is that they are environmentally better than traditional automobiles. It is in the top 4 reasons why people choose them ... next to because they look cool, the technology is incredible, and or you do not have to pay for gas. While it is true that electric cars are, environmentally speaking, much better than traditional ones, there is still a much better option.

When it comes to electric cars, their environmental impact is heavily dependent on the source (and cost) of the electricity that c... More →

Dr. Conca reports that new advances in batteries and storage technologies for electricity may soon solve one of the most vexing issues with wind and solar energy, dealing with their intermittency. The wind and sun generally do not generate power when it is needed, and we have not had efficient ways to store that energy, instead making other power plants, like hydro and gas, ramp up and down to accommodate.

Batteries have been our common method to store electricity, but they have always been small, inefficient and costly. Recent advances have produced large mobile batteries in the MW... More →

InsideEVs brings to this bloggers attention the major driving force behind the exponential growth of sales for EVs from the very low base. Cheap lithium batteries change everything and all cars will be electric by 2030. Elon Musk with Tesla Motors is doing this trick and now Tesla Model 3 will ignite the real transition to the best cars which just happen to be electric.

The oil and auto industry are poisoned by their own toxic cancer hazard emissions from diesel and gas powered ICE engines and still in denial at their own peril about the dramatic shift in technology, Elon Musk said... More →

Response ...In December, delegates from 195 nations meeting in Paris approved a remarkable global climate agreement. It calls for all countries to reduce emissions of greenhouse gases substantially. Most of these emissions currently come from the burning of fossil fuels, coal, oil and natural gas, and the message could not be more clear... we need to change the way we generate and use energy, and do so quickly.

Diarmaid Williams reports that the notion that the world can reliably be powered completely by renewable energy does not stand up to scrutiny, according to a leading expert on climate change.

Ben Heard, Director of Australia-based ThinkClimate Consulting, told the World Nuclear Association annual symposium in London that his organization did a thorough analysis of the body of literature supporting that 100 per cent renewables viewpoint, and found it lacking in supportive evidence. A world powered 100 per cent by renewables as popularly conceived does not exist. I can tell you it is ... More →

J. Winston Porter, of the GreenvilleOnline, opines that the growth of solar and wind power in the U.S. has spawned a really bad idea ... the notion that renewable energy sources can replace fossil fuels in electricity production.

Many states have been so keen to develop renewables that solar and wind power have grown at a fast pace. But much of this growth was made possible by generous federal tax credits for renewables. Now the solar and wind supporters are lobbying Congress to approve a multi-year extension of these tax credits, claiming that, without the credits, renewables can n... More →

Alexander E. MacDonald, et al., report CO2 emissions from electricity generation are a major cause of anthropogenic climate change. The deployment of wind and solar power reduces these emissions, but is subject to the variability of the weather. In the present study, they calculate the cost-optimized configuration of variable electrical power generators using weather data with high spatial (13-km) and temporal (60-min) resolution over the contiguous U.S.

Their results show that when using future anticipated costs for wind and solar, carbon dioxide emissions from the U.S. electricit... More →

That was before news that the European biggest economy might be running out of money for its green-energy revolution. The German $412 billion plan to power itself with green energy may be running low on cash, according to financial consultants, as consumer energy prices skyrocket and traditional power plants require more subsidies to stay in business.

The Climate Change Act 2008, which ties Britain into stringent environmental measures, should be suspended - and then scrapped - if other countries refuse to agree legally binding targets, says Owen Paterson MP. Britain will struggle to keep the lights on unless the Government changes its green energy policies, the former environment secretary will warn this week. Owen Paterson will say that the Government plan to slash carbon emissions and rely more heavily on wind farms and other renewable energy sources is fatally flawed.

Alex Trembath reports that the financial advisory firm Lazard recently updated its estimates for the levelized cost of different electricity generation technologies, and some observers were quick to highlight how wind and solar PV costs were called competitive with natural gas.

Regardless of subsidies, the wind levelized cost is competitive with gas, and has been for years. But the Lazard narrow and low range for solar PV is both surprising and inconsistent with other leading estimates from the U.S. Energy Information Administration, the International Energy Agency, and the Fraunho...

Michael McDonald opines that despite the fact that Elon Musk has built his company up from nothing amid extremely trying circumstances, while simultaneously upending the rocket industry with SpaceX, many investors continue to scorn Tesla. It was little surprise then that the Tesla announcement of its grid-scale battery systems was greeted with skepticism and outright derision in some quarters of the market. Tesla bears may come to rue that dogmatic view.

Julian Spector reports that it might be technically feasible, but that does not mean it is the best plan to pursue. But it is not clear that a U.S. energy grid based on 100 percent renewables is the best way to achieve a zero-carbon future. On the contrary, there is a strong environmentalist case for approaching that goal with caution. Limiting a zero-carbon future to wind, water, and solar means greater costs of storing this energy, discarding other existing zero-carbon sources like nuclear, and generally blanketing the earth with panels and turbines as a means to save it, plus likely greater...

Dr. Conca reports that the latest greatest utility-scale battery storage technology to emerge on the commercial market is the vanadium-redox battery, also known as the vanadium-flow battery. V-flow batteries are fully containerized, nonflammable, compact, reusable over semi-infinite cycles, discharge 100% of the stored energy and do not degrade for more than 20 years.

Most batteries use two chemicals that change valence (or charge or redox state) in response to electron flow that convert chemical energy to electrical energy, and vice versa. V-flow batteries use the multiple valence ... More →

As the need for alternative transportation fuels increases, it is important to understand the many effects of introducing fuels based upon feedstocks other than petroleum. Water intensity in "gallons of water per mile traveled" is one method to measure these effects on the consumer level. In this paper we investigate the water intensity for light duty vehicle (LDV) travel using selected fuels based upon petroleum, natural gas, unconventional fossil fuels, hydrogen, electricity, and two biofuels (ethanol from corn and biodiesel from soy)....

Despite the claims of advocates to the contrary, wind and solar continue to be the most expensive sources of electricity. The New York Times recently reported that wind power is currently more than 50 percent more expensive than power generated from a traditional coal plant.

Energy Secretary Stephen Chu told the New York Times that solar technology would have to get five times better to be competitive in the current energy market. In spite of these reports and admissions, the public relations campaign for wind and solar powered electricity marches on with misrepresentations.
