Amazing Changes Happening Now for Sustainable Living: Renewable Energy

Renewable energy has been booming, especially in the last couple years. Renewable energy resources have been around for a long time; however, their popularity has increased with the ongoing movement towards trying to slow down global warming. There are many forms of renewable energy that have been used, developed and installed even as I write this. Here are the largest forms of renewable energy and a little bit about their usage today.

Solar Energy

We are a solar company so of course solar is our favorite. Solar panels provide energy during the day, from practically sun up to sun down. There is so much solar energy to be harvested, that like many statistics and memes say, so much solar energy hits the earth that if we could power the needs of the world for 25 years or more in a single day of sun. The only problem with that is creating enough solar panels to harvest all that energy and then storing the power so it can be accessed after the sun goes down; however, there are people working on energy storage as we speak. Solar energy can also be used for other applications such as water heating or heating a building / home.

Wind Energy

Wind energy can provide a ton of energy day and night as long as the wind is moving. Today’s wind power is generated by a windmill turning a turbine that generates power to feed electricity to power lines; however, wind power has been used in the past for grinding grain and pumping water. Wind farms can be installed in a large open area or offshore and provide a lot of power to nearby areas. Storage of this power is still being developed, just like solar power; however, seems to be a more popular approach to large scale power generation. New developments in wind power are being made to harness wind power when there is little wind and windmills that protect wildlife from harm.

Geothermal Energy

Geothermal power extracts steam from underground and uses that to power turbines to generate power. The water is extracted during this process and fed back under the Earth’s surface to generate more steam. The main drawback to this form of power generation is the steam can carry a mixture of gases that contribute to global warming, bad smells and acid rain. These gases need to be contained and not put into the atmosphere.

Hydropower & Tidal Energy

Both hydropower and tidal energy uses the natural flow of water to turn turbines to generate power. Dams have been set up on rivers and underwater windmill looking devices have been setup on shores to harness this power. Since tides are more predictable than the winds or sun, tidal power is growing in popularity as a great way to harness power; however, there is still controversy in changing the natural flow of water and disturbing natural habitats.

Every form of renewable energy has its pros and cons; however, by combining forces and utilizing each form to its capacity, we will one day be able to move towards a more sustainable world. Here in sunny south Florida, solar will always be my favorite source of energy. What is your favorite and why?
