What's popular on EarthTechling? A monster offshore wind turbine, poo power at the Denver zoo and a solar-powered plane. Check it out:

1. This Offshore Wind Turbine is Quite the Monster — On hearing that France had a new goal to increase its renewable energy by 23 percetn by 2030, offshore wind companies leapt at the chance to get involved. One of the results is Alstom's giant 6-megawatt Haliade 150 offshore turbine, currently the world's largest offshore model, which is currently undergoing efficiency testing on land. If all goes well, offshore testing will begin in the fall.

2. Zoo Poo Powers Tuk Tuk in Denver — Denver Zoo's boasting a new method of transportation, a motorized ricksha purchased from Thailand known as a tuk tuk, is powered by elephant poo. No really. The vehicle is part of the Zoo's new program to convert 90 percent of its trash and animal waste into energy, and so the tuk tuk has been re-engineered to run on gasified pellets made of waste, human and non-human alike.

3. Geothermal Steams Forward, Under the Radar — We hear a lot about the advances and setbacks of solar and wind powers, but here's a look at renewable energy's underdog, geothermal power. This article talks about the specifics of geothermal, why it's a very viable renewable energy solution, and the newest geothermal projects going on in the U.S.

4. Solar Impulse Takes Aim at Fuelless Flight Record — The Solar Impulse, a completely solar-powered plane, will try to make it into the world record books by completing a 1,550-mile journey without any fuel other than sunshine. This run, scheduled for May or June, will beat its first, 340-mile journey from France to Belgium, and will entail a 48-hour flight over the Pyrenees.
