Solar Saves When the Grid Goes Down

From today’s Scientific American, Solar Power Helped Keep the Lights on in India.

Every day, at least 400 million Indians lack access to electricity. Another nearly 700 million Indians joined their fellows in energy poverty over the course of the last few days, or roughly 10 percent of the world’s population.

Oddly enough, some of the formerly energy poor—rural villagers throughout the subcontinent—found themselves better off than their middle-class compatriots during the recent blackouts, thanks to village homes outfitted with photovoltaic panels. In fact, solar power helped keep some electric pumps supplying water for fields parched by an erratic monsoon this year.

Local and diverse, though David Biello, the author of the article, argues that we need to look at the grid in the USA, or else stock up on flashlight batteries. You can read the rest of his short and interesting blog post here.

And here’s from the financial magazine, Forbes…

While national renewable energy policies – or the lack there of – remain mired in Congressional election-year politics, the great green future has already arrived in California.

On Tuesday, state regulators announced that California’s three big investor-owned utilities – Pacific Gas & Electric, San Diego Gas & Electric and Southern California Edison – had reached a mandated target – called the renewable portfolio standard, or RPS, to obtain at least 20% of the electricity they sell from renewable sources.

In 2011, the three utilities collectively secured 20.6% of the electricity sold to retail customers from solar, wind, geothermal and other renewable power generation.

Perfect time for the USA to win the energy race and lead the world in more efficient and cheaper solar and renewable technology. We’ve done this kind of thing before, that’s why our flag waves on the moon. Now it’s time to get serious about planet earth.

Africa Lights the Way

In the dark and cold season, with the snow blowing and a wind that cuts like a knife, here’s some warm and shiny news from Kenya…

KIPTUSURI, Kenya — For Sara Ruto, the desperate yearning for electricity began last year with the purchase of her first cellphone, a lifeline for receiving small money transfers, contacting relatives in the city or checking chicken prices at the nearest market.

Charging the phone was no simple matter in this farming village far from Kenya’s electric grid.

Every week, Ms. Ruto walked two miles to hire a motorcycle taxi for the three-hour ride to Mogotio, the nearest town with electricity. There, she dropped off her cellphone at a store that recharges phones for 30 cents. Yet the service was in such demand that she had to leave it behind for three full days before returning.

That wearying routine ended in February when the family sold some animals to buy a small Chinese-made solar power system for about $80. Now balanced precariously atop their tin roof, a lone solar panel provides enough electricity to charge the phone and run four bright overhead lights with switches.

The future is small, smart and decentralized. Will we win the energy race, or will we be buying Chinese solar panels because we did not invest in manufacturing our own? I have faith, and I believe that the prize for this race will be one giant step for mankind.

Also, read between the lines. Sara Ruto’s energy use is modest and focused on what is essential for her family. Conservation and non-wastefulness are part of the mix. I’m going to switch off a couple of lights now. If enough people do that it makes a difference.
