Arguments for renewable energy
Climate change. All renewable energy plans emphasize that they will leave a much smaller carbon footprint than current fuel sources used. The environment is better off as renewable sources do not produce toxic emissions and deplete our natural resources.
Stable energy prices. Fluctuations in the supply of fossil fuels have a direct effect on inflation. With renewable energy the cost is from the amount of money setting up the infrastructure and not dependant on supply and demand of natural resources. We can expect more stable prices from his scenario.
Micro-stations. From solar panels on homes to small wind farms, there are many different types of renewable energy that can be used anywhere. These micro-stations are low cost and reduce the waste incurred in transporting energy from major stations to the consumer.
Reduce our energy consumption. These renewable technologies are new to the world and many of the sources cannot produce that much energy in a short amount of time. This would mean we either have to build many more facilities to produce the same energy as fossil fuels or the more likely option of reducing our energy consumption.
Reliability. In most cases the flow of an energy source like the sun or flowing water are permanent and constant sources of fuel. Unlike fossil fuels which can be affected by wars, strikes and political instabilities renewable energy sources do not come with such restrictions.
