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
By Ariele Johannson – (San Diego’s East County)–Driving through the southwestern deserts, I’ve long been impressed by the ocotillo, a cactus-like tree with straight branches angling upwards to the sun, ablaze with red blooms. This thorny desert tree is an apt metaphor for the ways different people view energy issues– especially proposed industrial solar and wind power projects in remote wilderness areas. Like the ocotillo, these programs and policies have a wide array of angles from which to be viewed. … Continue Reading

Denmark’s Samso Island is a sort of paradise for renewable energy enthusiasts. The residents have created, in just over a decade, a 100 percent carbon neutral, self-sufficient community.The local Samso Energy Academy is an example for other areas around the globe who might want to create an economic environment that is good for the ecological environment. … 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
Ireland has the potential to produce three times the country’s energy needs using renewable resources.
Ambitious plans to capitalise on renewable opportunities in Ireland appear to have stalled and it remains to be seen if the Government can get things back on track, writes JOHN REYNOLDS
THE GOVERNMENT’S jobs action plan talks of building upon our Emerald Isle image and capitalising on opportunities, particularly in renewable energy, to “green” the economy. But has the dream faded? … 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
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 …
