Multiple sources of renewable energy are being developed around the world as countries try to reduce their dependence on fossil fuels. For the generation of electricity in particular, depending on the locale, solar, geothermal, hydroelectric, and wind energy are all being used. Of all the forms of renewable energy under development, I think wind has perhaps the most immediate promise. … Continue Reading

If Germany is to meet its ambitious goals of getting a third of its electricity from renewable energy by 2020 and 80 percent by 2050, it must find a way to store huge quantities of electricity in order to make up for the intermittency of renewable energy. … Continue Reading

The EPA today proposed new limits on carbon pollution from new power plants. Environmentalists say the move will be a boon to Floridians, who get about 25 percent of their electricity from coal, but utility reps say the rules will “crush jobs” and arrest America’s economic recovery. … Continue Reading
The Washington Post reported this evening that the Obama administration plans to propose the first nationwide standard to reduce carbon dioxide pollution from new power plants:
“The Environmental Protection Agency will issue the first limits on greenhouse gas emissions from new power plants as early as Tuesday, according to several people briefed on the proposal. The move could end the construction of new conventional coal-fired facilities in the United States.” … Continue Reading

A new assessment of wind energy in India has found that the potential for on-shore wind energy deployment is far higher than the official estimates — about 20 times and up to 30 times greater than the current government estimate of 102 gigawatts. This landmark finding may have significant impact on India’s renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity. … Continue Reading
Solar is becoming very affordable for buyers
By DIANE CARDWELL - Last year seemed like a dark one for the solar industry: Stiff competition from China drove American manufacturers to layoffs and even bankruptcy, while the low price of natural gas and the loss of a critical government subsidy weakened incentives for new solar developments. And then there was the long shadow of Solyndra, whose bankruptcy after receiving federal loans cast a pall over other green-energy endeavors. … Continue Reading
by Dana Blankenhorn – With natural gas prices having tanked, and the President being given stick on the campaign trail over high gas prices and failed subsidies at Solyndra and elsewhere, it may be hard to see that the War Against Oil is being won.
But it is.
The War Against Oil is a long-term project, begun some years ago, meant to wean the market from its dependence on fossil fuels and create a new era of sustainable abundance. It is at the heart of today’s politics, oil interests having taken command of our politics 12 years ago and retaining an absolute stranglehold on the Republican Party. But this is, in the end, an economic struggle, and what ultimately matters is cost. … Continue Reading

With so many major items before the U.S. and the rest of the world, the main topic during the past few weeks in the U.S. has been about contraception and birth control. One would think Women’s Rights and related issues have long been settled.
Aren’t there more pressing and immediate concerns Congress and therefore, the Media should be discussing. For example; What about Energy? How about an Energy Policy which includes renewable energy standards; and as an extension, what about Gas Prices – how high is it going and why? What about our Importing Oil – how do we eventually become independent of foreign oil? Are we simply suppose to “drill baby drill” or as others decry, immediately and totally cease all oil and coal exploration and its’ use, or as President Obama requested, have an “all-of-the-above” strategy?
The issues of expanding drilling capacities, the expansive inclusion of solar power, wind power, biomass/biofuels, hydropower, geothermal power, natural gas, and nuclear power are far more pressing to the nation and the world at large, both immediately and also to our future. Instead we’re left to hear talk and argument about old and long settled matters, and of impossible ways to “fix” the past.
An energy policy for the United States has become like the weather: everyone talks about it, but no one ever does anything about it. This lack of consistent direction has created volatile, and recently, sharply negative returns to investors in the Alternative Energy space. With a lot of hot air being generated in the months …

Despite the availability of clean and sustainable energy sources like solar, wind, hydropower, geothermal and biomass, many states depend on outdated and dirty energy sources. Ohio, Pennsylvania, Indiana, Missouri and Tennessee are among the most in need of an energy portfolio diversification. The Natural Resources Defense Council (NRDC) has identified solutions for these and other …

Demand for solar PV energy in the U.S. continues to gain considerable traction. During 2011, installed PV capacity reached the 2 GW level, with 880 MW allocated to the commercial sector and 760 MW to the utility segment. However, this growth has not been realized without certain challenges. Indeed, often years of negotiation take place …

When somebody mentions renewable energy, most of us think primarily of methods we can use for home production, namely wind turbines and solar panels. However, there are a number of alternative energy sources still waiting to break through into the public conscience. Airborne forms of wind power are arguably some of the most exciting amongst …

Sustainable Energy and Renewable Energy are terms that are thrown around a lot these days, but what exactly do they mean, and how many countries are taking them seriously? The US Energy Information Administration (EIA) estimates that in 2008, 10% of the world’s energy consumption was from renewable energy sources. EIA forecasts that by 2035, consumption …

Since 2006 Bonded Logic, an Arizona-based cotton fiber insulation manufacturer, and Cotton Incorporated, an association of cotton manufacturers, growers and retailers, have teamed up to change the final resting place for approximately 200 tons of unwanted denim from the landfill to new homes in the United States, in the form of denim insulation. The “Cotton. …

A new study of renewable energy’s technical potential finds that every state in the nation has the space and resource to generate clean energy. The U.S. Department of Energy’s National Renewable Energy Laboratory produced the study, U.S. RE Technical Potential, which looks at available renewable resources in each state. It establishes an upper-boundary estimate of …
