Our Energy Sources

Two questions immediately strike us: Will we have enough affordable energy in the near future? What will we do for the long term?

The answers depend on our inventory of sources. Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun. Electricity falls into its own category because it’s an energy carrier and not a primary source. Here we explore the pros and cons of each resource and look at some of the emerging technologies that could transform our energy situation in the future.
