  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. The best unreasonable of these sponsorships are pointed at finding new saves of coal, oil and gas, even though it is usually understood that these must be left in the ground if we are to avoid catastrophic irreversible climate change. Alternative energy does have some setbacks when depending on them totally. Spikes in electricity bills happened in Southern Australia when 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. Solar panels are the representation of the 'green power' movement, however the process of manufacturing the silica based panels can be detrimental to the environment. Raw silica is used to create solar cells that must be mined while using harsh chemicals that harm the surrounding environment, as well as those who are working in the mines.
