The price of oil has stabilized since last summer’s SUV-stalling spike, but our supply of oil—a finite resource [...]

Instead, advanced-technology coal power sits on the shelf while regulators wait to see what happens with a project that may be just an expensive boondoggle.
Solar, wind and other renewables generating at least 25% of our electrical energy backed up mostly by natural gas fired turbines and maybe a few more nukes is the most likely scenario over the next 25 years. As coal plants retire, a mix of new renewables and gas fired plants will take their place.
Often derided by his lesser known contemporaries who toiled away in scientific obscurity, Carl Sagan was an all too rare breed of scientist – a marketer with the soul of a poet. We could use a few more Carl Sagans to help us see things more clearly. Help us to develop and maintain perspective about [...]
The “tragedy of the commons” articulated by Garrett Hardin in 1968 is now being played out on a planetary scale on our ultimate “commons”, the global climate in which we all live.
