Rooftops, great for shelter, can now make the homeowner money too. That’s because of renewable energy technology. People are able to generate their own electricity close to home, and in communities where utility companies allow it, they can sell whatever they don’t use to the electric company.
Homeowners, farmers and businesses also are installing their own wind turbines, with the same benefits. Consumers are becoming producers and part of the energy marketplace.
Home-based solar and wind systems are good for the environment, good for local economies, and part of a larger global trend that relies increasingly on renewable energy resources.
California-based energy expert Angelina Galiteva calls renewable energy a “win-win-win” development. Renewables, she says, are “not only the lowest-cost alternative and the most environmentally benign alternative, but they are also the greatest job creator.”
Renewable energy resources — sun, wind, water and even garbage — are rich and inexhaustible sources of clean electricity and fuels. “The fuel price of solar and wind is not going to go up,” Galiteva says, because “the sun will come out. The wind will blow.” Now we need to build the infrastructure globally to take full advantage of these natural assets.
Jobs and economic empowerment
Renewables affect job markets and work opportunities in several ways:
- Workers are needed to manufacture, build and maintain equipment, especially for solar and wind.
- Technicians who worked in the fossil energy industry are being retrained for the renewable energy industry.
- When renewables bring electricity to remote, rural communities, more people can work at home and the younger generation can study — on mobile devices.
- Innovators and entrepreneurs have new opportunities and incentives to develop and market refined, affordable energy technologies.
“Renewables are an empowerment tool,” Galiteva emphasizes. Because distributed energy generation is local, it strengthens communities around the world economically and socially.
Big business is coming on board
More utility and technology companies are committing to 100 percent renewable energy for two main reasons. “It’s a business decision and an environmental decision,” Galiteva says.
Apple, for example, is building its own microgrid, which will supply electricity to the company’s new Cupertino facility. “They are going to be generating 100 percent of their energy on-site, but they are going to be interconnected to the grid,” Galiteva says — so the excess energy they generate will flow into the general power supply. “They think it is exciting to participate in the energy market.”
Apple recently joined Renewables 100 Policy Institute, with other influential companies pledged to achieving 100 percent of their power from renewable energy. The diverse roster of Renewables 100 companies includes IKEA, Adobe, General Motors, ING, Wal-Mart and H&M, among others.
Among utility companies, Pacific Gas and Electric is upgrading its facilities to meet the needs of California customers who are becoming energy producers. “I’ve seen the new distribution control centers for PG&E,” Galiteva says. “They are getting ready to become a distributed energy aggregator.” Which means PG&E will more efficiently combine and utilize smaller power sources — distributed energy resources — to meet regular demand.
Another company banking on renewables is the giant U.S. Berkshire Hathaway Corporation, owned by business magnate Warren Buffet. This multifaceted company is prioritizing renewable energy in its utility holdings. MidAmerican Energy in Iowa — part of Berkshire Hathaway’s energy portfolio — announced this year it will shift to 100 percent renewable energy without increasing cost to customers.
It’s not just about environmental responsibility, it’s about income, creating jobs and becoming a good corporate citizen, Galiteva says, adding, “The fact that it is good for business is what really makes it work.”
