Surprise! US Leads World in Wind Energy Production

Due to our land area advantage, strong winds, and newer, more efficient turbines, the US has overtaken Germany as the world’s largest producer of wind energy in terms of megawatts produced. This is a great step in the right direction, and being the world-leader in wind energy production could do a (very) little damage control for the US’s energy-hog image around the world. Germany has the capacity to produce up to 23,000 megawatts of power. The US only has a capacity of 18,000 megawatts. However, the strong winds across our landscape (especially Texas) make our fewer wind turbines more productive. Also, Germany’s wind energy also accounts for 7% of the country’s total energy usage, while our wind energy only accounts for 1.2%. Denmark, by comparison, gets 20% of its power from wind. So we still have room for improvement, especially in the area of power transmission. It would be shame to generate the world’s most wind energy, only to lose more than half of it to inefficiencies in transmission.

Overshoot, Collapse, and Creating a Better Future

There’s a lot more you could be […] Read More

Save Energy & Money This Winter: Seal Up Your Drafty House

Unless you’ve taken special preventative precautions, it’s likely that on cold days much of your house’s heat pours out through your (closed) windows. Most houses—especially old houses—have drafty, uninsulated windows that do little to prevent heat from dumping out into the cold night. Even if your windows aren’t drafty, the expensive heat your furnace has […] Read More

The Limits to Growth and Greece: Systemic or Financial Collapse?

Could it be that the ongoing Greek collapse is a symptom of the more general collapse that the Limits to Growth model generates for the first two decades of the 21st century? Author Ugo Bardi (Extracted: How the Quest for Mineral Wealth is Plundering the Planet) examines the correlation between what is unfolding between Greece […] Read More

Designing Your Own Solar Cooker & Dehydrator

In today’s world, nearly everything we use, from phones and computers to cars and kitchen appliances, requires energy derived from fossil fuels. Wouldn’t it be nice to offset some of that energy use by harnessing the renewable power of the sun? Josh Trought, founder of D Acres—an educational center in New Hampshire that researches, applies, […] Read More
