Biofuels And Jet Travel

Global communication and global travel have transformed economic life in our world and have been important tools in improving quality of life for many. They have transformed our world’s culture in ways that we do not yet fully understand. Let’s take the first small steps in building the technology and business models most appropriate to a renewable resource-based sustainable economy.

Turning Sunlight into Fuel

The world uses little more than one percent of the sun’s energy for our electricity needs. A major obstacle to tapping into its full potential is that it is intermittent. Solar fuels could one day store, transport and use solar energy to produce electricity and replace fossil fuels in vehicles.

California’s First In The Nation Climate Plan

The goal of the energy transition is to create a renewable energy system that is as effective and reliable as the current fossil fuel-based system. Microgrids provide backup capacity and vastly increase the reliability of power systems for consumers. A second goal of the energy transition is to switch off of fossil fuels and rely on solar, wind and geothermal sources of energy.
