Guest Blog: America’s Solar Future: The View from Beijing

Tom Rooney, CEO of SPG Solar, rings the solar gong at the SunTech solar factory in China.

Greetings from Beijing where, from my cafe seat near Tiananmen Square,  plans to expand solar power in the United States look a lot different than from my office in Northern California — where I am the CEO of one of America’s larger solar power companies.

Many of the measures — and half measures — that we read about every day in American papers are things the Germans and Chinese and Spanish and French decided to do 10 years ago.

They are racing. We are walking.

Germany, for example: Hardly a sunny hot spot — but it has more solar installations than any country in the world. 200 times more than England. That is because German citizens have been getting 50 to 75 cents per kilowatt hour for the solar power they sell back to the grid. Spain is similar.

Great Britain and France and Ontario and other places throughout the world recently raised their so-called ‘feed in tariffs’ to  comparable levels.

In Gainesville, Florida, the feed-in tariff is now the highest in the country at 32 cents. All of a sudden there is an explosion of interest in solar in Gainesville.

In California, we get less than 10  cents. And that is more than most places.

In the United States, we limit not just the price but also the amount of solar energy an owner can sell back to the grid. So we wait for the day when all the transmission lines are perfect. When the grid is perfect. When all the energy infrastructure is in place.

Meanwhile, we wait for an energy future that may never come.

If we allowed the price to rise, and removed the limits on how much solar energy a farmer or business owner or school or police station could generate, we would see an explosion in demand for solar and other renewables.  That would reduce our dependence on foreign energy and stimulate domestic manufacturing, as well.

It’s a two-fer.

That is our best chance of creating solar panel manufacturing jobs in the United States. But it is already very late in the game.  Michael Northrop of the Rockefeller Brothers Fund points out the most of the world’s largest renewable energy manufacturing happens outside the United States. He says,  “Not only are we shipping oil dollars to the Middle East, we are watching our solar, wind, and other renewable energy dollars begin flowing to Asia. … The U.S. needs to decide rapidly whether it wants to own this future or pay for it.”

From my seat in Beijing, where I am traveling the country visiting suppliers for my solar power installation company, it looks as if this decision has already been made.

Bat Fatalities at Wind Energy Turbines Offer New Insight into Bat Migration

By Simmons Buntin, January 20, 2010 5:26 pm

After visiting Carslbad Caverns with my daughters this spring, I have a new affinity and respect for bats and their migrations. (In truth, I’ve always been a fan of bats, but more so even now.) So this recent update from the Journal of Mammalogy strikes a chord:

Bat fatalities at wind energy turbines offer new insight into bat migration

New data suggest that bats, like birds, may follow specifically defined routes when migrating rather than simply migrating in a dispersed way across a broad area. Wind energy turbines located in these routes may cause fatalities of migrating bats. As new sources of energy such as wind farms are being built in greater numbers, their impact on other aspects of the environment must be considered. While we reduce carbon emissions and develop renewable energy resources, we must be careful not to endanger migrating species such as bats.

The migratory behavior of bats, a topic that has received little attention in the past, is the subject of new study in the December 2009 issue of The Journal of Mammalogy. Wind turbines have been the cause of many bat fatalities, but these installations also offer a new opportunity to examine bat migration habits. This is because the majority of bat fatalities caused by wind turbines around the world have involved migratory bats during fall migration.

Over a period of seven years, scientists used acoustic monitoring and carcass searches at nine wind energy facilities across southern Alberta, Canada, to determine if bat activity and fatality were concentrated in certain areas or evenly distributed across the landscape. Their findings indicate that as bats migrated, they concentrated along selected routes at night and sought daytime roosting sites. Migratory tree-roosting bats, including hoary bats, eastern red bats, and silver-haired bats, are the North American species most affected by wind farms.

As locations and types of turbines are planned for new wind energy facilities, the information gained from studying the migratory habits of bats can be put to use, making the facilities even more environmentally friendly. For instance, the researchers found that greater tower height increased the probability of bat fatality, but that differences among sites in migratory bat activity also were related to the number of bat fatalities. By identifying migratory routes and the specific landscape features that bats follow, bat fatalities could be minimized by building wind facilities in areas with low migratory activity.
