Summary
As alternative to fosil fuels, renewables are welcomed by greens and seen by governments as tools to combat climate change. With subisidies from governments in both developed and developing countries, the past few decades saw growth in renewables. Yet renewables only account for 7% in the world's energy, while fosil fuels take up 80%. But their subsidy-driven growth did push their price down. Yet if they continue to penetrate into the energy market, it will not only hurt traditional energy industry, but also pose difficulties for the renewable industry itself.
Except the facilities, generating wind and solar power themselves does not cost a dime. That means the more renewables created, the more they are likely to drag down energy price. This will drive some traditional energy companies out of the market and, moreover, hurt the renewable producers themselves. For if the price goes down, so will private investors' profitablity and their willingness to pour money into this industry. Yet as the industry expands, it needs more financial support. With decreasing private investment, the government will be pressured to give renewable producers more subsidies.
Another flaw for renewables is their intermittency. So it's impossible for us to totally depend on renewables; we also need traditional energy when no wind or sunshine is available.As for the customers of traditional companies, some will shift to renewables. And those who continue to use fosil fuel generated energy have to bear higher price given the decreasing demand. Moreover, in California home generators are allowed to fed excessive energy from their solar panels into the gird; the grid is complaining about the payment.
To ensure enough fossil- fuel capacity available, the government need to subsidize more to those companies. Yet some of these fuels,like brown coal，are dirty. In the long run ,we can build a smart system combined with renewables and standby fossil fuel capacity and make it a package deal. The customer pay for the service to ensure continued supply of electricity under this system. Yet today's grid system were not built for remittant solar and wind power. So investment are needed to make sure facilities including a smart grid system in place. That may arouse political issues for citizens may complain about higher prices to support these investments and possible blackouts.
The progress may be slow and renewables are not expected to power every home.
