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 the U.S. wants wind power, The Great Lakes are definitely windy.
Illinois and four other states came a step closer to offshore wind farms in the Great Lakes (New, April 1), and that is welcome news. Wind farms, once mocked by climate skeptics and opponents of renewable energy, are now a profitable way to generate clean electricity for our homes and businesses. … Continue Reading
A holistic, renewable electricity system would generate millions of good jobs
WASHINGTON, DC (ENS) – The leaders of the United States, Mexico, and Canada today pledged to develop “continental energy, including electricity generation and interconnection” across national borders and welcomed “increasing North American energy trade.” … Continue Reading
Hydrogen storage tanks presently used in hydrogen-powered vehicles
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
Ebay's Utah data center
by Mindy Lubber, reposted from Forbes
When eBay, the world’s largest online marketplace, built its first-ever data center in South Jordan, Utah, it wanted to not only design and build the site to LEED Gold standards, it wanted to use clean energy to power much of the sprawling facility. This wasn’t simply part of eBay’s company-wide commitment to sustainable operations, it was a bottom-line business decision: sourcing renewable energy would stabilize and reduce long-term energy costs and minimize environmental impacts in a state that gets 94 percent of its electricity from coal. … Continue Reading
Since President Obama entered office three years ago, renewable energy production in the US has climbed 26.9%, according to the Energy Information Agency’s (EIA) latest “Monthly Energy Review.”
For the three years ending November 30, 2011, domestic oil production has also risen, by 13.7%, natural gas production grew 13.4%, nuclear power decreased by 2.8% and coal production plummeted by 7.3%.
For the first 11 months of 2011, renewables accounted for 11.76% of domestic energy production, up from 10.83% for the same period in 2010.
In terms of actual production, renewables rose 13.4% in 2011, with hydropower supplying 34.9%, followed by biomass (26.6%), biofuels (22.0%), wind (12.7%), geothermal (2.4%), and solar (1.3%). … Continue Reading
China seeks major advancements in renewable clean energy
BEIJING – China has established its first national think tank on renewable energy to conduct research and develop programs and policies, as part of the country’s effort to deal with climate change and carbon emissions.
The China National Renewable Energy Center, launched on Thursday, will also draft industry standards and carry out international cooperation programs. … Continue Reading
For four decades, Amory Lovins has been a leading proponent of a renewable power revolution that would wean the U.S. off fossil fuels and usher in an era of energy independence. In an interview with Yale Environment 360, he talks about his latest book, which describes his vision of how the world can attain a green energy future by 2050.
Amory B. Lovins is fond of referring to the Rocky Mountain Institute, where he serves as chairman and chief scientist, as a “think and do” tank, and it’s clear that to Lovins the doing is every bit as important as the thinking. Hardly lacking in confidence or ambition, Lovins — in conjunction with his colleagues at the institute — has published Reinventing Fire, his step-by-step blueprint for how to transition to a renewable energy economy by mid-century.
Amory Lovins
Impressive in both its scope and detail — Lovins discusses everything from how to redesign heavy trucks to make them more fuel efficient to ways to change factory pipes to conserve energy — the book lays out a plan for the U.S. to achieve the following by 2050: cars completely powered by hydrogen fuel cells, electricity, and biofuels; 84 percent of trucks and airplanes running on biomass fuels; 80 percent of the nation’s electricity produced by renewable power; $5 trillion in savings; and an economy that has grown by 158 percent. … Continue Reading
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 …

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 …
