Sometimes the ingenuity of mankind is nothing short of awe-inspiring. This is especially true when it comes to using various forms of alternative energy to create electricity. A review of ideas that are being promoted and employed in countries around the world make for interesting reading and might even renew your faith in humanity! Consider the following.
- Sewage-generated power. For years we have been adding to the massive amounts of garbage that continues to pile up around the world. Well, today there are nations that have learned how to capture the methane gas that emanates from the sewage as it’s on its way to treatment plants. The gas is then used to power generators and create electricity!
- Natural resource generated power. There are several natural resources that have been harnessed to generate electricity in the United States and elsewhere. These include wind, solar power, hydropower, and geothermal power. Let us examine each one a bit more closely.
- Wind farms have popped up all over the globe. Wind turbines are used to harness the natural power of the wind. Once bulky and unsightly – technology continues to make them less obtrusive and more valuable to the generation of electricity.
- Photo voltaic power is the most common type of solar power in use today. Solar panels have been around for several decades now and the technology continues to advance. Concepts such as ‘thin film’ technology make solar power more accessible and reasonable. Solar farms are also becoming more widespread. They capture heat that is used to warm water and create steam. The steam then powers generators to create electricity.
- Hydropower can be seen in the form of wave farms. This equipment is installed near oceans for the purpose of capturing wave energy and converting it to electric power.
- Geothermal energy is defined as the thermal energy that is stored and generated within the earth itself. Tunnels are drilled into the earth to access the planet’s natural heat where water is warmed and converted into steam which is then used to power generators.
Additionally, more buildings and homeowners are going ‘off the grid’. This is possible due to advances in electric generation that makes it easier to create the power necessary for singular use.
