Renewable Energy in Winter

The Beer: Found a new on-line resource. Beer100.com. Check it out.

The Bicycle: Always be sure your bicycle in securely in the trainer before climbing on. Otherwise, it can hurt. A lot.

The VRWC: More reasons why "renewable energy" can never be the panacea the Eco-whackos want.

Fact is, renewables will never be reliable enough to meet all energy needs. They will remain a niche at best. Recall that the sun shines at about 1000 watts per square meter....at the equator.....at the equinox....at noon.....on a perfectly clear day. In these here parts, this time of year, it's about 300 watts per square meter and doesn't get much better than 500-or-so. And remember, that's peak. Anything off optimal conditions reduces the available energy significantly. And oh...solar panels are only 10-15% efficient.

Anyway, read the article. It's illuminating (no pun intended).
