Rooftop Solar Calculator Tells You Your Roof’s Solar Power Potential

The whole key to an efficient rooftop solar power system is finding the right roof in the right spot with the least shade, and now a team of scientists has developed a new system (a solar calculator) that can provide visual images of the rooftop solar potential for any existing building….

Livestock Production, Environment, and Going Green

Several months ago, back in June of 2010, I wrote up a story on the environmental impact of eating meat based on a new-at-the-time United Nations (UN) report on the matter. I recently ran across another good story on this topic on a friend’s site, Global Warming is Real, titled “Eating Less Meat to Cut CO2 Emissions” that resulted in a follow-up.

Could Los Angeles be Solar-Powered?

On the same day that the catastrophic 9.0 earthquake hit Japan, March 11, UCLA’s Luskin Center for Innovation announced the publication of its “Los Angeles Solar Atlas.” Needless to say, it didn’t get much attention at that time. But it is a very useful and interesting publication, so I thought I’d share some of its key aspects and findings with you today.

Can Pigs Fly?

A survey released two weeks ago in conjunction with National Butchers’ Week suggests that many British consumers think that pigs can fly.

Poplar Leaves Inspiration & Model for Energy-Efficient Cool Roof Technology

The fast-growing poplar tree is starting to build up its cred as an all-around resource for the sustainable future, and its latest contribution is in the area of new cool roof technology. A research team in China has developed a waterproof coating that mimics the leaf’s highly efficient reflective properties, which could lead to a new generation of roof-cooling materials.

Food Prices on the Rise — Expect that to Stay the Same

Worldwide, high crude oil prices, increasing extreme weather events, population growth and economic development of poorer countries, crop-based biofuels, political conflict and unrest in the Middle East, and slowing crop yield growth are all factors contributing to rising food prices.

Solar Power in a Carrying Case

OS – a Japanese company that makes retractable screens for projectors – has invented this very handy portable solar power-on-the-go device, that sells for ¥60,000 – or about $730.

Scotland Plans World's Largest Underwater Tidal Turbine Project

Iberdrola subsidiary ScottishPower Renewables plans to install a tidal power project between two islands, Islay and Jura, in the inner Hebrides off the west coast of Scotland. The expected power output of the £40million project will be 10 MW, enough to power twice the number of homes on nearby Islay.
