Lighting the Way to Solar Power

Fact one: The earth receives more energy from the sun in just one hour than the entire world uses in a whole year.

Facts two through four: According to the US Environmental Protection Agency, electricity generation is the largest single source of greenhouse gas emissions in the US, accounting for 30 percent of all such emissions in the 1990s, compared with 26 percent from vehicle emissions. And burning coal also produces toxic particles of cadmium, aluminum, lead, nickel and sulfur, much of it falling on working-class communities. Additionally, transmitting this generated energy over high tension wires wastes as much as two-thirds of the energy originally created.

The electricity we rely on is polluting, wasteful, and expensive. Essentially, the energy industry in this country is mired in 19th-century thinking, and the veiled faces behind Vice President Cheney’s energy policy are fighting hard to keep it there.

In parts of the U.S. and around the world, however, energy companies are paying consumers who have switched over to solar power for their homes and businesses to supply the grid with their excess energy. Some areas even have subsidies for those who install solar power in their homes.

In the San Francisco Bay Area, a $21,000 investment in solar panels will bring about $10,000 in refunds and cut your energy bills down to nearly nothing. On top of that, more than half of state governments have what's called "Net Metering" laws on the books. This means that the energy utility company must pay the consumer retail costs for excess power generated by solar, at least up to their average monthly consumption.

So instead of using an outdated, wasteful and dirty method of generating electricity, the public could switch to solar energy and save money in producing it; save health costs by having cleaner energy; and protect the environment all at once. It sounds like an environmental fairy tale, but the technology is available and is rapidly dropping in price. As more people start buying solar generators, they become more affordable to manufacture, thus allowing more people to buy them and lowering the price ever further. It's just a matter of getting the ball rolling.

And while many people (especially those who live in the White House) seem to think that converting to renewable and efficient energy is unnecessary and difficult, around the country groups are working to make it happen.

In 2001, San Francisco voters overwhelmingly passed a public bond measure that would fund $100 million in renewable energy projects and conversion to more energy-efficient technologies. A revolutionary step in sustainable urban living, this bond measure, created by the Vote Solar Initiative, costs voters nothing, since the bond money comes from the energy savings in converting to solar power.

David Hochschild, one of the founders of Vote Solar and an architect of the initiative, calls this a truly groundbreaking piece of legislation. "We've got a very aggressive agenda in San Francisco. Thanks to the overwhelming support of the voters, we're sending a clear signal to Washington that the people want change on our energy policy, and it's starting here."

Vote Solar unveiled its first major San Francisco project on Nov. 21 -- it is also the first major governmental solar project in the nation. At 1.3 million square feet, Moscone Center is SF's largest convention center. The $7.4 million solar retrofit includes plans for installing solar panels on the roof of the center and upgrading its internal lighting with more energy efficient methods, including motion sensors connected to light switches and more efficient bulbs. Compact fluorescent light bulbs, which cost from $3 to $8 apiece and are growing in availability, can last up to seven years and will save about $30-$80 more in electricity costs than the original investment.
