This is my fourth annual list of renewable energy and energy efficiency stocks since I began the series in January 2008, which I expect to outperform in 2011.
What is the variability problem of wind and solar energy, how serious of a problem is this and what can be done to fix it? This article examines this issue of variability, describing and defining it and listing some of the ways in which the unique challenges of wind and solar energy is being or can be addressed.
Will electric cars one day become part of a network of rechargeable batteries that can help smooth out the intermittent nature of wind and solar power? Many experts believe so, pointing to programs in Europe and the U.S. that demonstrate the promise of vehicle-to-grid technology.
In the coming years, electrical contractors will transition into “energy contractors” to support the fast-growing green construction market. There has been a revival of interest in the electrical trade as home owners and corporations adopt alternative methods (e.g. solar, wind, etc) to power buildings. What’s driving this? Federal incentives, lower material costs and savings from reduced energy spending.
A new study reveals that nuclear energy and other traditional energy supplies like fossil fuels cost are and will continue to rise and not likely ever go back down. Meanwhile, renewable energy has achieved a “downward cost curve” over the last decade, and they are likely to continue to fall in price.
Many energy experts contend natural gas is the ideal fuel as the world makes the transition to renewable energy. But since much of that gas will come from underground shale, potentially at high environmental cost, it would be far better to skip the natural gas phase and move straight to massive deployment of solar and wind power.
The first comprehensive update to Unites States wind potential estimates in 17 years helps renewable energy proponents by providing solid data for development and legislation. However, the wind power industry needs an improved electrical grid in order to transport and sell wind-generated energy…
Studies show that corn based ethanol may nearly double greenhouse gas emissions instead of reducing them. Does Algae pose the same risks as corn? Are biofuels the wrong way to go when it comes to identifying fuel sources?
