New, ‘hidden’ source of renewable energy fights for tax breaks
Waste heat: It's everywhere, and we're wasting it. (Hence the name.) Giant industrial processes throw off enormous amounts of the stuff, all of it not quite hot enough to be usable in conventional power generation. That's where the waste heat industry comes in. Using liquids that boil at temperatures significantly lower than water, they've created […]

Denmark’s government throws down the gauntlet: 100 percent renewables by 2050
Lots of people talk about the possibility of getting to 100 percent renewables by such and such a date — if every one of these reports came true, we'd be exporting surplus wind power to the asteroid belt by now. But few countries are actually doing it. Denmark is one. And Denmark would like you […]

Cost of adding tons of renewables to U.S. electric grid has been almost zero, say studies
Many states have "renewable portfolio standards" mandating that they produce a certain percentage of their electricity from renewable sources. Libertarian and tea bag-ish critics of these standards have said that they will cause electricity rates to "skyrocket." But the numbers are in, and guess what? Science says the critics are wrong. Utility companies’ experiences vary […]

Making power lines beautiful with the help of a giant reindeer
Here's the down side of increased renewables: It means an increase in unsightly overhead power lines. And if you can't put them underground (which isn't always feasible), the answer might lie in turning an eyesore into a triumph of design. Germany is abandoning nuclear and embarking on a big renewables push, but to make it […]

Why Germany had to phase out nuclear to build its renewables
Lots of American journalists (including this one!) have gone on and on about renewables and nuclear power in Germany without having a first-hand appreciation of the situation, or even any German language ability. This has led us all to misapprehend some pretty basic facts about why the Germans decided to phase out their existing nuclear […]

U.S. finally catching up to rest of world on solar
In the U.S., solar photovoltaic (PV) panels are, somewhat unexpectedly, suddenly the belle of the renewable energy ball — and their dance card is wide open. There is now more solar PV capacity planned for the immediate future than any other renewable you can name. Wind, solar thermal, geothermal — it's like they all showed […]

Saudi Arabia scrambling to get off own oil, build 5 gigawatts of solar power by 2020
What do you do when you're basically a giant welfare state whose stability depends on keeping the money tap open, yet your population is set to double and your electricity consumption to triple by 2032? If you're Saudi Arabia, the answer is build renewable energy as fast as you can. The first volley is a […]

Rwanda to power itself with plentiful, domestic geothermal energy
If the first thing you think of when I say "Rwanda" is "Don Cheadle looking worried while a radio booms 'Hutu Power!' in a basso profundo," it's time you updated your thinking. The country is currently looking into meeting its need for electricity by tapping into the hot rocks that underlie much of the country, […]

Offshore wind power to explode to 17 times its current capacity in just six years
Offshore wind will reach 70.1 GW of capacity by 2017, says Pike Research. That's 17 times its current capacity, which is 4.1 GW, and amounts to several times the current maximum solar capacity of the most solared-out country in the world, Germany. Europe is currently in the lead on offshore power, but by 2017, China […]
