Fish Waste Biodiesel Project Launched in Vietnam

What to do when your corner of the world consumes 5 million liters of diesel fuel a day and you have a fish processing industry which can produce 120,000 kilograms of processed fish waste daily from just one factory? Turn that waste into biodiesel, obviously.

Tropical Forests Better Left Intact As Carbon Sinks Than Converted to Biofuel Plantations

That may be an obvious statement for regular followers of renewable energy news, and of the green movement in general, but a new study published in Conservation Biology illustrates just how important intact tropical forests are in slowing climate change. And just how counter productive converting them to biofuel plantations really is.

Jet Engine Wind Turbine Design Could Halve Wind Power Electricity Costs

Until some carbon taxes or a cap-and-trade system pushes fossil fuel prices up to where they probably should be (if all the environmental factors are taken into consideration) any small thing that reduces the cost of generating electricity from renewable energy sources is great news.

15% of Iowa’s Carbon Emissions Come From Ethanol Plants, More Than Belching Cattle

OK, before anyone accuses me of a misleading headline: Coal-fired power plants in Iowa produce much more carbon emissions than do ethanol plants. Said. Done.

Poo Power To Provide 25% of US Forest Service’s Electricity

While we’ve covered both consumer green energy programs and the animal waste-to-electricity projects a number of times, this is the first combination of them that I’ve seen. And I can thank action by the US Forest Service for bringing it to my attention.

The Forest Service has announced that it will be offsetting 25% of its electricity usage through payments made to the Vermont-based CVPS Cow Power.

$92 Million Algae Biofuels Deal Signed Between GreenFuel Technologies & Aurantia

Of all the biofuel feedstock options currently on the table, the only one with a real shot of displacing significant quantities of fossil fuels is algae. To date there have been a number of participants in the race to produ...

With the completion of a new 194 MW wind farm off the coast of Skegness, Lincolnshire the United Kingdom has overtaken Denmark to claim the offshore wind power capacity crown. The new installation brings the UK’s total offshore wind capacity to 590 MW, which is approximately enough electric generating capacity for 300,000 homes.

Solar-Powered Electric Cycle Rickshaw Debuts in Delhi

While it is easily possible to argue about the human rights aspect of pedal-powered rickshaws (there’s certainly a bit of difference in the type of people involved in the biz in India compared to their limited use in the United States...), there’s no denying that from an environmental perspective they’re a better form of transport than burning fossil fuels.

Carbon Neutral Olive Oil: Italian Farm Will Cut Its Carbon Emissions 100% in One Year

photo: Maury Landsman

While I’m not sure that the claims by the owners of Castello Monte Vibiano Vecchio olive oil farm that they will be the first farm anywhere to reduce their net carbon emissions to zero, without using offsite carbon offsetting projects, are be entirely true—I’d be surprised that some small farm hasn’t tried to do the same thing, just not publicized it as well—the efforts by the owners of this Umbrian farm are pretty interesting: ...

Don’t Just Take it From Me: IEA Warms Up to Feed-in-Tariffs for Renewable Energy

photo: Bernd Sieker

As Renewable Energy World correctly points out, the International Energy Agency “isn’t exactly a hotbed of progressive thought” when it comes to renewable energy. But it seems that the IEA is slowly coming around. In a recent report the agency touts the benefits of feed-in-tariffs as a comparatively inexpensive and effective tool in promoting renewable energy deployment.

Renewable Energy Economy 101: Lester Brown Updates Us On the Story So Far

In case you’re new to the “new energy economy” debate—in short, figuring out how to transition the entire energy infrastructure of the world away from fossil fuels and towards renewable energy—and want as about brief a summary as could be created of the progress made in the last year as well as some of the challenges ahead, this one’s for you.

DIY Solar Heater from Recycled Campaign Signs

Using Corrugated Plastic to Heat Your House
OK, so the video might be a little over long, but the idea is neat. Using corrugated materials to create a forced air heater that can supplement the heating in your house. And while the demo version is built out of cardboard, presenter Dan Rojas suggests that in about a month's time there will be a fair amount of corrugated plastic signs littering people's yards across the US that could be about perfect...

US’s First Feed-In-Tariff For Solar Power Could Be Adopted by Gainesville, Florida

Now that the legislative dust seems to have settled and the issue of renewable energy tax incentives resolved, at least for the time being, in the United States it might be tempting to overlook the following announcement coming out of Gainesville, Florida, but you shouldn’t.

London Array, World’s Largest Offshore Wind Farm, Gets Another Backer

One of the largest wind farms in development, onshore or offshore, the 1 gigawatt London Array just got one step closer to reality. Abu Dhabi’s Masdar— of self-proclaimed zero carbon city and alternative energy investment fund fame—just announced that it has acquired a 20% stake in the project.

Put Green First & Promote Solar Power with the Vote Solar Initiative

Though renewable energy in general, and solar power in particular, has really planted itself firmly in public consciousness over the past year, that doesn’t mean that individuals can rest on their laurels. One of the most interesting booths at Solar Power International wasn’t even on the exhibit floor, and wasn’t even staffed by anyone.

30-Fold Increase in Solar Power Possible by 2016, If Solar Industry and Utilities Collaborate to Make it Happen

One of the renewable energy policy developments to come out of Solar Power International comes in the form of the Solar Electric Power Association laying down a gauntlet in front of US electric utilities. The industry trade group has outlined four policy guidelines which it says will allow the nation to “see an increase in solar capacity of more than thirty fold between 2009 and 2016.
