As any observer of the energy scene can confirm, renewable energy is providing an increasingly large portion of our energy needs. Photovoltaic solar panels are cheaper than coal. Geothermal and wind are competitive with other fossil fuels. We have the technology to phase out the internal combustion engine and to massively reduce the energy wasted in inefficient buildings. We can switch from fossil fuel to bio-diesel for most engines currently sucking fossil fuels and overloading our atmosphere with greenhouse gases.
