While renewable energy has a long history, renewable power sources such as wind and solar power play a relatively small role in the modern energy economy, which is dominated by fossil fuels. Most plans for significantly reducing carbon emission rely heavily on these renewable energy sources. This could involve trillions of dollars of investment in renewable energy projects in the coming decades. Project finance will likely play a major role in funding these investments.
