Renewable energy is energy generated from natural resources such as sunlight, wind, tides, waves and geothermal heat, which are naturally replenished.  Carbon mitigation efforts need to introduce substantial amounts of clean, renewable energy.  Possibilities include wind, solar, geothermal, and biomass, as well as off-campus renewables.  Investing in renewable energy research and technology can contribute to a reduction in emissions on our campus so that we can meet our future goals.  The U of I will satisfy at least 5 percent of all its electrical energy needs through renewable energy generation systems by 2015, and add more renewable energy sources during the future.
