Emerging Technologies and Alternative Energy
Alternative energy is an energy source that is an alternative to fossil fuel. All these alternatives are intended to address concerns about such fossil fuels, such as its high carbon dioxide emissions, an important factor in global warming. Hydroelectric, marine energy, wind, solar power and geothermal are the alternative sources of energy. The nature of the constitutes of an alternative energy source has changed significantly over time, as have arguments regarding energy use. This will lead to less use of coal, oil and gas thus prevent these sources from depletion. Spikes in electricity bills happened in Southern Australia when the wind was not driving the turbines responsible for a huge portion of the counties power. This led to the government to reintegrate a gas-powered station which will supply the power while the wind turbines were powerless. Even though solar energy is renewable form, the creation of solar panels requires silica to be mined and used thus affecting the environment.
