Renewable Energy: Land Use and Cost Concerns

Coal-fired power stations and nuclear power stations each have about 40 hectares of footprint, with a very narrow target transmission lines straight to the cities. In contrast, solar and wind installations are scattered and located away from the main cities, taking up enormous amounts of space. Their energy density is very low, requiring a vast amount of land to produce the same power, and they aren't on consistently. This increases transmission costs and the amount of land that regions must devote to solar, wind, and now batteries, causing significant angst.

Around the world, every country that has increased the proportion of solar and wind has also increased the cost of electricity for consumers and destroyed their manufacturing base. For example, look at Germany.

A surface coalmine must pay a bond for every hectare uncovered each year, and if it is rehabilitated properly to a superior standard than it was originally, they get their money back. However, there is no such bond for solar and wind companies to set aside funds for decommissioning their complexes at the end of their life. This needs to change!
