These are exciting times in the energy industry. We see a convergence of trends in society that are driving the transition to a world powered by clean electricity. Wind and solar energy have become large global industries whose products are scaling up now and changing the way power is generated and delivered. They are compelling sources of energy that have been enabled by technology. They produce no carbon emissions, they consume no water, and they are now cost competitive. Renewable energy resources are making an important contribution to meeting the needs of our energy-driven lifestyles.
