I would suggest reading the book 'Sustainable Energy without the hot air', its freely available on the author David Mackay's website:

It is a great read with a lot of understandable number crunching about different sources of energy, losses, end to end calculations of emissions and carbon footprints, etc.
Renewable energy technologies have an enormous potential and that potential can be realized at a reasonable cost. Market research shows that many customers will purchase renewable power even if it costs somewhat more than conventional power. However, both economic theory and experience point to significant market barriers and market failures that will limit the development of renewables unless special policy measures are enacted to encourage that development. These hurdles can be grouped into four categories:
1-commercialization barriers faced by new technologies competing with mature technologies
2-price distortions from existing subsidies and unequal tax burdens between renewables and other energy sources
3-failure of the market to value the public benefits of renewables
4- market barriers such as inadequate information, lack of access to capital, "split incentives" between building owners and tenants, and high transaction costs for making small purchases
