For China to be willing to reduce its use of coal-fired power plants that cause CO2 emission alternative energy source must be priced not higher than the price of power generated by coal. This will be possible if there shall be sufficient technological innovations in the production of clean energy at such low prices. Market incentives for such innovations have a good chance of success, according to Friedman (2007, p.50). Without the benefit of new technology, the world community can reduce the rate of carbon emission by (1) using alternative energy to coal such as gas, nuclear, ethanol and solar, (2) reducing the consumption of electricity at homes, offices and factories, and (3) controlling the amount of CO2 emission by reducing the burning of forests and capturing the amount of carbon from coal burning.
