For anyone who has read a recent article about solar energy vs. fossil fuels, it might appear as if solar energy has already won the battle.
Dr Robert Crawford, Deakin University, Australia presents the results of a net energy analysis that compared solar and conventional hot water systems for a southern (Melbourne) and a northern (Brisbane) Australian climate.doi:10.1016/S1471-0846(01)80076-7Robert H. Crawford...
When comparing solar energy vs fossil fuels, there are several factors to consider; emissions, cost, and availability. In our opinion, solar wins the argument on emissions and availability. Traditionally, fossil fuels would have won the cost argument, however, solar is becoming cheaper each and e...
The International Energy Agency says solar is now the cheapest form of electricity for utility companies to build. Tough break for fossil fuels.

Here, we calculate global time series (1995–2011) energy-return-on-investment ratios for fossil fuels at both primary and final energy stages. We concur with common primary-stage estimates (~30:1), but find very low ratios at the final stage: around 6:1 and declining. This implies that...
