Reducing the use of fossil fuels reduces greenhouse gas emissions. By reducing electricity demand during a conservation period, Peak Rewards also reduces emissions by averting the need for production of additional electricity. When load is highest and supplies are strained, the least efficient power plants must be brought into operation to meet demand or outages become likely.
Lower efficiency electricity production also generally equates with higher emissions. The Peak Rewards approach reduces the urgency in building additional power lines and power stations, thereby preserving our natural environment.
