So alternatives can include solar energy and wind energy. Solar energy has multiple advantages, including the fact that it is infinite and does not cause pollution. Likewise, wind energy is infinite and makes excellent sources of energy in remote areas. However, solar and wind energy are not always available. Solar energy depends on the time of day and weather in each country, while in some areas the wind is not strong enough to generate electricity from wind turbines. Additionally, solar panels and wind turbines are expensive to manufacture and both take up large areas of land. Many argue that ecosystems and habitats are being destroyed by the construction of solar panels and wind turbines, even if they do not cause pollution..
