It’s always a thrill when people I’ve known since my childhood grasp the opportunities that renewables represent. When my brother Geoff and I were teenagers, we had a fine friend, JR Castle (James Rutherford, if I’m not mistaken), who came …

Frequent commenter Larry Lemmert waxes metaphorical with the respect to our clean energy targets: We need to go after the low-hanging fruit before climbing the tree and going out on a limb to harvest energy that has a negative payback …
Tomorrow my daughter and I will spend the afternoon on a project for her science class at school: building a model house whose electrical power is delivered with solar photovoltaics. I have a small solar panel that (I believe) will …
I had a lovely phone chat last evening with a young lady, a high school senior who was working on a paper for school and wanted to ask a few questions about solar energy. In particular, she wanted to know …
Here’s a good article on the solar photovoltaics industry by consulting giant McKinsey and Company. Not to give anything away, but they share my belief that the PV industry is in a momentary lull, not a swan song. Best of …
You can see lots of attention is focused towards alternative and renewable energy systems. This is due to the soaring energy costs and the need to decrease the climate change effects over earth. Though these solutions may seem complicated for …
For amusement only…. Today I cooked mashed potatoes in my solar oven. The oven is made of one of those shiny windshield shades, a rack from an old countertop oven, a very large clear plastic pretzel container and a 2lb …

Here’s an article that gets to a couple of important points that are illustrative of where we are and where we’re going in clean energy. • Financing solar photovoltaics. There is no doubt that homeowners would be more likely to invest …
Germany has installed enough photovoltaics that, at this point, coal-fired power plants are beginning to become unprofitable. This is driven by a combination of factors, e.g., that coal isn’t asked to provide power at the peak of the day, when …
I’ve often written about how astonishingly little of the Earth’s surface needs to be covered in a solar collecting technology, e.g., solar thermal, in order to provide 100% of the world’s energy needs. Linked above is a wonderful graphic that …
