Top Green Power Users

For the first time, a corporation ­leads EPA's national Top 25 list of green power purchasers. Wells Fargo & Company claimed the top spot, purchasing 550 million kilowatt hours annually. Organizations that purchase electricity generated from clean, renewable resources such as solar, wind, geothermal, biogas, biomass and low-impact hydro make up the quarterly list. After Wells Fargo & Company, Whole Foods Market ranks second and the U.S. Air Force ranks third. The U.S. EPA ranks fourth, with Johnson & Johnson rounding out the top five. Newcomers to the list include Cisco Systems Inc., New York University, Carbonfund.org, the U.S. Department of Veterans Affairs, and Kohl's Department Stores.

EPA's Top 25 green power purchasers are buying more than 4 billion kilowatt-hours of green power on an annual basis. This is equivalent to the energy needed to power more than 350,000 average American homes each year. The EPA Green Power Partnership encourages organizations to purchase green power as a way to reduce the environmental impacts associated with the use of electricity from fossil fuels and to diversify America's fuel supply. The partnership is comprised of a diverse set of organizations including Fortune 500 companies, small and medium businesses, government institutions as well as colleges and universities. EPA's Top 25 Green Power Partners is as follows, listed in order of purchase size:

1. Wells Fargo & Company

2. Whole Foods Market

3. U.S. Air Force

4. U.S. Environmental Protection Agency

5. Johnson & Johnson

6. Starbucks

7. DuPont Company

8. U.S. Department of Energy

9. Vail Resorts Inc.

10. HSBC North America

11. Cisco Systems Inc.

12. Staples

13. New York University

14. The World Bank Group

15. University of Pennsylvania

16. IBM Corporation

17. Carbonfund.org

18. U.S. Department of Veterans Affairs

19. NatureWorks LLC

20. Sprint Nextel

21. Safeway Inc.

22. Pennsylvania State University

23. Kohl's Department Stores

24. Commonwealth of Pennsylvania

25. The Tower Companies

So what? Well, if you're interested in putting your money where it may do some good (or at least less bad), buy some groceries from Whole Foods, take a loan from Wells Fargo, or buy some staples at Staples.

Geothermal Energy

NPR had a bit about a new geothermal energy study performed by MIT which claims that "...mining the huge amounts of heat that reside as stored thermal energy in the Earth's hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact." So all we need to do is drill down a mile, inject water which is boiled by the earth's heat, and channel the steam back to turbines on the surface. Sounds great.

There are a few drawbacks, among them being a shortage of water in the parts of the country where the hot spots are most readily available (west), and the possibility that drilling into and fracturing rock may cause earthquakes like this one in Switzerland.

I honestly haven't heard of this type of geothermal energy before, but am familiar with the geothermal heating and cooling available in all sizes. I've been in a home equipped with a system that simply had the pipes laid underground throughout the yard. I've also seen them work very well with the pipe coils in nearby ponds or lakes. I commented on TreeHugger here about how geothermal deserves a lot more press.

Fort Wayne is actually home to a large geothermal company called WaterFurnace International, as well as some smaller businesses.

If you are in the market, please do a little research on geothermal for your heating and cooling. You will be amazed at what it has to offer.

Wind 1

I'm betting you've all heard a least a little of the controversy over wind turbine farms. Most of that controversy is based on a view that the turbines are "bird blenders". The other big problem is a perception of decreased property values.

Celsias has a post that does a good job presenting the animal vs. turbine arguement.

As with all new energy technologies, buying your own unit is expensive and may not ever pay itself off. I did some research for a foundry and, for any turbine smaller than the utility-scale 5MW jobs, the payback period was ∞. The cost of a 5MW unit is around $1.5 million.

For more info, check out The US Dept. of Energy Wind Power site, including whether wind power is even feasible in your location by searching for your windmap.

Gold, Myrrh, and ...

Cinnamon? How about Lavender?

According to a recent study, the trees from which Frankincense is made are becoming tapped-out, and younger trees are not rising to the occasion.

This is a great anecdote for one of the big problems facing renewable (environmental friendly) products. The supply side must be very carefully monitored when demand increases, or else unintended consequences almost always arise. Frankincense, like all agriculture, is renewable, but by not properly managing the supply, the supply may suffer serious declines.
