Clean Energy Demand and Supply.
                     CLEAN ENERGY: 
DEMAND AND SUPPLY
Introduction
• Renewable energy, often referred to as clean energy, comes from natural sources or 
processes that are constantly replenished. 
• For example, sunlight or wind keep shining and blowing, even if their availability 
depends on time and weather.

ENERGY SOURCES
Solar energy
• Solar energy is the fastest growing and most affordable source of new electricity in 
America. 
• As the cost of solar energy systems dropped significantly, businesses have taken 
advantage of clean energy.

Wind power
• Wind power is one of the fastest-growing renewable energy technologies. Wind is used 
to produce electricity using the kinetic energy created by air in motion. 
• This is transformed into electrical energy using wind turbines or wind energy 
conversion systems.

Water energy
• Water energy is energy derived from the power of water, most often its motion. Energy 
sources using water have been around for thousands of years in the form of water 
clocks and waterwheels.

Geothermal energy
• Geothermal energy is heat within the earth. The word geothermal comes from the 
Greek words geo (earth) and therm (heat). 
• Geothermal energy is a renewable energy source because heat is continuously 
produced inside the earth.

Hydrogen
• Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. 
Hydrogen can be produced from a variety of domestic resources, such as natural gas, 
nuclear power, biomass, and renewable power like solar and wind.

Demand
• Energy demand patterns are largely driven by our activities. Peaks in demand exist 
simply because, at certain times of day, there are a lot of people doing a lot of things 
that all require electricity.

Supply
• When treated as a strategic asset rather than a tactical expense, renewable energy 
provides cost and risk benefits across the supply chain.
