Unlike coal, solar energy is non toxic and creates clean energy without harming the environment. The problem with clean energy sources is that they are more expensive to maintain and create than coal plants. Also the amount of energy that solar, wind, hydropower and geothermal generate is way lower than what a coal-fired plan can generate. "it would take four wind farms or seven solar generators to replace one coal-fired plant generating similar output. Solar generation costs $189,000 to match 1 megawatt per year generated by coal, and wind power is nearly as expensive"(Andy Tully). This ratio proves how much less efficient and more expensive clean sources are than fuel based energy sources. Another factor that decreases the popularity and efficiency of clean energy sources is the fact that not all the time the wind is blowing in high speed or the sun is not exposing enough heat for the solar panels. Such downsides cause investors to invest their money in coal based power plants regardless of how much damage it might cause to the environment. Without enough money or funding scientist cannot break through scientific barriers that limit their capability to
