California is leading the way in providing renewable energy as part of the overall energy portfolio for Californians – and business is leading the way in producing innovative solutions to get there.
What is renewable energy?
Renewable energy comes from natural sources or processes that are constantly replenished. This includes wind, solar, geothermal (using heat within the earth’s crust, e.g. geysers), and biomass.
Renewable energy is one way the state of California is using to reach our climate energy goals. By converting sources provided by our environment, electricity, transportation and other areas can be fueled effectively with minimal greenhouse gas emissions.

Renewable Natural Gas (RNG)
Though we typically hear about benefits of wind and solar and its contribution to clean energy – one exciting new source is renewable natural gas.
Natural gas, which consists largely of methane, has traditionally been sourced from decomposing organic matter found underground (ie. fossils). However, there are other sources of decomposing organic matter that can generate natural gas. One example is a landfill, which produces gas from its decomposing organic waste. Renewable Natural Gas is captured from the organic waste and converted into energy. Replacing less than 20 percent of the traditional gas supply with RNG captured from sources like dairies, wastewater treatment plants and landfills can achieve greenhouse gas (GHG) emissions reductions equivalent to converting 100 percent of buildings to electric only energy by 2030.
Renewable Natural Gas can be produced from a variety of existing waste streams and renewable biomass sources, such as:
- Animal waste from dairies
- Food waste from landfills
- Organic waste from wastewater treatment plants
- Organic waste from landfill-diversion facilities
