Energy Efficient Business Attire
Wool Suits and Ties in August?
One hot August day, I organized a luncheon in New York City where the President of the Philippines gave a speech to about 150 bankers and business leaders. When I say it was hot, it was a day that defined sweltering. You could see the heat waves rising from the asphalt. Arriving early to make sure everything was ready, I found that the luncheon hall had been refrigerated (air-conditioned would be a gross understatement) to feel like a walk-in freezer. >More Megacities and Environmental Catastrophes
What to do with the old cities?
All over the developing world, ultra-modern megacities are being built.

A kilowatt-hour (kwh) generated by your solar power system in the afternoon is worth more than a kwh generated in the morning. So it makes sense to generate more kwhs of solar power in the afternoon, even if that means your solar power system loses more kwhs of potential generating capacity in the morning. >More |
