SAN FRANCISCO -- Google, the Internet search and advertising giant, is increasingly looking to the energy sector as a potential business opportunity.
From its beginning, the company has invested millions of dollars in making its own power-hungry data centers more efficient. Its philanthropic arm has made small investments in clean energy technologies.
But in recent weeks, Eric E. Schmidt, Google's chief executive, has hinted at the company's broad interest in the energy business. He also joined Jeffrey R. Immelt, General Electric's chief executive, to announce that they would collaborate on policies and technologies aimed at improving the electricity grid. The effort could include offering tools for consumers.
