Different Green Energy: Things to Consider

If the human race is to survive, we’re eventually going to have to switch over to completely renewable energy. At the moment, most of our energy comes from natural gases, coal and oil based energy sources. These energy sources are both dirty and unsustainable.

A 2009 study by the Lawrence Berkeley National Laboratory identified seven major household energy uses:

  •     Space Heating—29%
  •     Space Cooling—17%
  •     Water Heating—14%
  •     Appliances—13%
  •     Lighting—12%
  •     Other (stoves, ovens, microwaves, coffee makers, dehumidifiers)—11%
  •     Electronics (computers, monitors, DVD players, TVs)—4%

What other alternatives do we have?

Improving your home’s energy efficiency, energy-efficient household means reducing its energy consumption by using efficient appliances and implementing energy-savings strategies.

DID YOU KNOW? Strategically placed landscaping, can also provide energy-saving and money at home. When you in comes to heating and cooling your home.

Efficiency works together with conservation—changing your energy-use behaviors (for example, turning off the lights when you leave a room, or dialing the thermostat back to 65°F at night). Apply the basic principles of conservation and efficiency to all of your energy choices, before looking at harnessing renewable energy.

Five different types of Green Energy.


Hydropower is currently the largest producer of green energy, accounting for over 70% of our renewable energy production.

The way it works is that special installations are placed underwater, where strong currents of water will push through a mechanical instrument known as a penstock.

This “push” is then converted into electricity and fed into the energy grid.

Solar PV

Solar energy is another common type of green energy. There are two main types of solar power: solar power for homes and solar power plants.

Though solar PV has gotten a lot of press in recent years, there are a lot of problems still.

First of all, though the production of energy is more green than oil, the process of creating the materials solar PV is made of is quite toxic.

Also, to make your money back from the savings of a solar panel may take as long as ten to twenty years.

Wind Power

Wind energy is a stellar renewable source of power. The key to wind power is to place these energy generators in high altitude, high wind velocity locations.

The return on wind power is quite substantial. The only downside is that aesthetically they block the view from just about any angle because of their size.

That said, wind power is more cost-efficient than solar and easier to construct than hydropower.


Geothermal energy isn’t applicable everywhere, but when it is the amount of energy generated can be very substantial.

Geothermal works by tapping into the earth’s intrinsic heat. It turns that heat energy into power and uses that as electricity.

In order to use geothermal, a high-heat underground spot must be identified.


Biomass is primarily the conversion of manufacturing by-products into electricity.

These by-products can include wood chips and fragments, leftover sugar, animal manure and anything else that’s burnable.

Biomass can also include materials produced specifically for the production of energy (e.g. corn ethanol).

The biomass is burned and the heat energy is turned into electricity. Biomass is a great way of disposing of products that might otherwise become waste; but is unlikely to become a primary producer of our world’s energy needs.

These are our primary sources of renewable energy. Of course, there are many other fringe sources of energy that are being researched all the time.
