Two large U.S. corporations have announced commitments to solar power.

Costco – the giant discount retailer – is installing its first solar array on the Kailua-Kona store in Hawaii. A 680-kilowatt solar electric system – big enough to power about 111 Hawaiian homes – will be installed by REC Solar of San Luis Obispo, CA. It’s expected to be completed in the next five or six weeks.

The Kailua-Kona store may save up to a one-third of its electricity costs by producing its own energy from the sun. Costco has more solar planned for other stores, mostly in Hawaii and in California.

A Safeway store in Dublin, CA has started generating electricity from its own solar panels, and the company plans to install systems on 23 of its stores – enough to power about 20 percent of a stores’ average energy use. That’s enough to avoid over 10 million pounds of carbon dioxide emissions (CO2) – a major contributor to global warming.

Efficiency is another part of Safeway’s plan: Since 2005, super-efficient refrigeration systems and LED lights have been installed that have allowed the company’s stores to do the same amount of work using less energy.

Companies may be scrambling to expand their green credentials, but they’re also moving forward because of ample incentives from the states. In Hawaii, commercial photovoltaic systems are eligible for credits of up to $500,000 and net metering laws are in place that allow companies to offset electric bills with surplus power put back on the electric grid. Additionally, the federal government offers a 30 percent tax credit.

Local, state, and national incentives for renewable energy will continue to drive business to do the right thing by making it economically sensible to do so. That, combined with a better brand reputation among consumers and investors, may drive even more companies to choose greener options.
