Wind energy can be a very reliable renewable energy source if the wind turbines are placed in the right location. The main disadvantages of this form of energy are; sight and noise, as well as wind turbine designs affecting avian life.
Solar energy can be somewhat unreliable depending on the placement, location, and surrounding environment of the solar cells. The greater the solar energy supply, the more effective the cells will be; however, the more heat a solar panel receives, the more unreliable it can be. Solar also has a somewhat long return on investment without government incentives.
Tidal energy can be used to create electricity from the large energy force behind the tides. The main disadvantage of tidal energy is the effect on the surrounding environment, affecting sea life, and shore access.
Wave energy is similar to tidal energy, but instead uses the force behind the waves to generate electricity. This is a relatively new technology, and in many cases, is still in the research phase.
Nuclear Power, has such an infinite supply fuel that it is considered sustainable, even though it’s not renewable. It’s totally clean when air and water pollution are considered. The big downsides are safety of the power plants and the long term effects of waste storage. The emotional arguments against nuclear power are an additional downside that also has to be regarded as important in any energy solution discussion.
Biomass is renewable energy, but not totally “clean”. Although significantly cleaner than most fossil fuels such as coal and oil, it still produces sulfur dioxide.
HydroElectric energy is a very clean and powerful method for generating electricity from a trapped wall of water. The undesirable side effect is the cost to the surrounding environment and limited locations where it’s optimum.
GeoThermal energy is a reliable energy source but it’s just not available in that many areas and therefore is not very scalable as a solution.
Natural Gas burns cleaner than other fossil fuels, is easily transported, and is efficient, but it’s still a pollutant. It’s not sustainable, of course, and the largest reserves are in the Middle East and Russia.
Coal is inexpensive, versatile and available in some abundance in the United States with an estimated 25% of the world’s known reserves. It’s not renewable, and acts as a pollutant contributing to acid rain and carbon dioxide release.
Wood energy ties in with biomass, as it is still renewable, but must be burned during electricity production, which makes it harmful for our environment.
Oil requires no discussion with regards to green energy except as a stop-gap to bridge us to green, alternative, renewable, sustainable, scalable, and independent sources of energy.
