Well, we have to produce electricity from something. Being against building anything at all is not a solution. Neither is conservation. You cannot power your computer on energy conservation. The power must come from somewhere to begin with. Environmentalists are against usually against coal plants, nuclear plants, hydroelectric plants. Yes hydro. Sometimes the argument is think about the fish which cannot swim upstream, other times it is think of the destroyed sunken ecosystems, other times it is dead plant matter at the bottom causing CO2 and methane emissions. Wind power is noise pollution and dead birds. Geothermal causes earthquakes. Solar pollutes water streams because of the solvents used in silicon manufacturing. So yeah, make sure to keep burning that natural gas.
