6:13 PM | As the water drops, so does the power.
As I empty the last of last month’s big snowstorm from my rain barrels onto the garden, I notice the water comes out more and more slowly. It’s a reminder of why power production drops as supply in our big reservoirs declines. Some tricky tradeoffs here:

4:57 PM | New Rooftops In France Now Have to Be Covered In Plants or Solar Panels
On Thursday (3/20), French legislators approved a bill decreeing that the rooftops of all new buildings built in commercial zones must be partially covered by solar panels or plants. These so-called “green roofs” provide increased insulation for buildings, which helps with temperature control. By absorbing more of the sun’s rays than a traditional roof, green roofs reduce the amount of energy needed to cool a building in summer. And during the winter, green […]

7:25 PM | How Anxiety and Guilt Affect Your To-Do List
Do you keep a running to-do list that never seems to end? Do self-directed commands such as “send emails” or “write resume” or “buy salad ingredients” always end up on tomorrow’s list because of a lack of time today? You may even find yourself saying, “There just aren’t enough hours in the day!” A new […]
6:04 PM | How Will The EU Energy Grid Handle The Surge During And After The Solar Eclipse?
The solar eclipse due to cover much of Europe on March 20 will be the continent’s first for 16 years. Back in 1999, as people stopped staring at the sun and got back on with their day they caused a power surge which still stands as a UK record – greater than anything after a football match or royal wedding. read more

engadget:Underwater Aussie wave farms pump both power and waterI’m super intrigued by this. Also, ocean-power in general. I mean, there’s so much ocean! And finding suitable space on land can be very challenging. I know the ocean-power alternative energy field isn’t as robust as its land-based counterparts, but I’d really love to see more work like this, esp since this *seems* like an environmentally safe setup.

One Step Closer to Solar Power Beamed From SpaceWireless energy is a hot topic now, but in Japan they’ve big thinking big about this for some time. In fact, i remember a few years ago mentioning this program (x): Their plan is to build solar panels… in space. Sounds a bit crazy, but consider this: In space there’s no clouds and constant sunlight, which is great for solar and often an issue for us grounders. The challenge, though, is getting that space solar energy back to […]

7:58 PM | Climate Pledges May Not Be Enough
The European Union (EU) is now the second body to submit an official climate target to the United Nations ahead of talks to reach a global climate agreement in Paris later this year. One of the world’s top emitters, the EU intends to reduce its emissions 40 percent (relative to 1990 levels) by 2030. This…

Plants capture sunlight and turn it into starch. Scientists are now adapting the photosynthetic process to improve the way we harness solar energyThe impacts that people have upon the global environment has been a concern to scientists for more than 100 years. These impacts are due, in large part, to the fuels we use. To reduce environmental damage, people must develop and use alternative fuel sources.“The one source of energy that is abundant across the developed and the developing world […]

The search for alternative energy sources in the age of climate change has overlooked tidal energy: a vast and unexploited worldwide resource.For three decades now, tidal lagoon schemes have been recommended as an economically and environmentally attractive alternative to tidal barrages. More recently, two proposals for tidal lagoons in Swansea Bay, Wales have emerged and there have been several reports documenting how such a project there could have the potential to harness significant energy […]

9:54 PM | Hospitals, Large Stores Could Use Natural Gas Fuel Cells And Get Off The Electrical Grid
Walmart, Costco and other 'big box stores' or facilities like hospitals could use a fuel cell that runs off the natural gas that already flows in pipelines below city streets and eliminate the electricity 'middle man', which is good for the environment. Instead of drawing electricity from the power grid, that often ends up being converted from coal, natural gas or nuclear power, facilities could instead go direct and use natural gas-powered solid oxide fuel cells. It would  lower […]
