Biomass energy. (click on link)
Using biofuels for your vehicle, buying clean electricity and products created from biomass, and heating with wood and pellets.

Geothermal energy.
To heat and cool your home, in some countries you can buy clean electricity from geothermal power plants, green power.

The Earth’s heat, which constantly flows outward from its core, provides an enormous source of energy called geothermal energy.  This could be a rich source for future renewable energy

Hydrogen.
Hydrogen and fuel cells can provide energy, another sources for green power.

Hydrogen—a colorless and odorless gas—is the most abundant element in the universe. However, because it combines easily with other elements, it’s rarely found by itself in nature. Hydrogen usually combines with other elements, forming organic compounds called hydrocarbons. Hydrocarbons include plant material and fossil fuels such as petroleum, natural gas, and coal. Water is produced during the burning of any hydrocarbon.

Hydrogen can be separated from hydrocarbons through the application of heat—a process known as reforming. Currently, most hydrogen is made this way from natural gas. An electrical current can also be used to separate water into its components of oxygen and hydrogen. This process is known as electrolysis.

Currently, hydrogen has great potential as a power source for fuel cells. Hydrogen fuel cells can provide heat for homes and buildings, generate electricity, and power vehicles.

Hydrogen can also join electricity as an important energy carrier. An energy carrier moves and delivers energy in a usable form to consumers.

Hydropower.
Energy from flowing water can be converted to electricity, this source of green power has been around for a long time. Flowing water creates energy that can be captured and turned into electricity. This is called hydropower or hydroelectric power.

Ocean energy.
Oceans cover more than 70% of the Earth’s surface. As the world’s largest solar collectors, oceans generate thermal energy from the sun. They also produce mechanical energy from the tides and waves. Even though the sun affects all ocean activity, the gravitational pull of the moon primarily drives the tides, and the wind powers the ocean waves.

Solar energy.
Solar energy can be used for heat, electricity, and light.  Step outside on a hot, sunny day, and you’ll experience the power of the sun’s heat and the light. That’s solar energy.

You can use solar energy to do the following:

• Heat your home through passive solar design or an active solar heating system
• Generate your own electricity
• Heat water in your home or swimming pool
• Light your home both indoors and outdoors
• Dry your clothes. Use a clothesline to reduce the energy consumed by your clothes dryer.

Wind energy.
Wind can be used to generate electricity and pump water.  We have harnessed the wind’s energy for hundreds of years—from windmills that pump water or grind grain to today’s wind turbines that generate electricity.

If you live on at least one acre of land with an ample wind resource, you can generate your own electricity using a small wind electric system. You can also use a small wind turbine for pumping water.

You may have the opportunity now or in the future to buy clean electricity from a wind power plant
