First, there is the economic dependence on the countries extracting them. Second, they exacerbate the greenhouse effect with their massive emissions of carbon dioxide. Renewable sources are expected to curtail this trend. Hydropower as well as solar and wind energy are considered to be viable alternatives. But they are dependent on advanced technologies to achieve greater efficiencies.
