There
are no technological or economic reasons why the
US and the rest of the world
cannot largely
completely
replace fossil fuels with renewable sources of energy over
the next 20 years.
- A recent study by Stanford researchers found that using existing technology, the world can abandon fossil fuels and adopt renewable energy in as little as two decades.
- The National Renewable Energy Laboratory’s (NREL) also released a study on Renewable Electricity Futures which found that using a diverse array of commercially available technologies, the US could easily supply 80 percent of its electricity needs with renewables by 2050.
- The Union of Concerned Scientists also recently published a plan for renewable energy to provide 80 percent of our electricity by 2050.

With
regards to cost/benefits, in
addition to curbing climate change causing greenhouse gas emissions,
renewable energy will also
contribute to improved
human health. Minimizing climate impacts and reducing health costs
would generate trillions of dollars of cumulative savings and
generate hundreds of thousands of new jobs.
Cost
and political will are challenges that will need to be addressed, but
the bottom line is that its
going to happen - it's just a matter of time. For
all our sakes, though, the sooner the better.
Germany currently generates about 25% of its electricity by renewable energy sources and expects to generate 35% of its electricity from renewables by 2020. This has created a problem during certain times of day when the surge of solar and wind power flooding into the grid exceeds the demand for electricity, resulting in negative prices. Similar situations are starting to occurr in Hawaii, Texas, New Mexico, etc. - Read "The Zero Marginal Cost Society" |
The
following are a few selected links to alternative energy sources that
we need to consider using in cities and states across the U.S.
Several
alternative energy technologies that are often forgotten in
discussions include Micro-Hydro and Micro-Wind solutions. Check out

Finally, South Carolina is actually
in pretty good shape as we move forward with the transformation of
our state's Energy infrastructure - and our citizens seem to be very
receptive to the changes that need to be made. See collection of recent

The model can be used by water systems that set volumetric charges for water as well as systems that only charge flat monthly fees.
