energy sources, and in many cases also on clearing forests.
The moral of the story, in essence, is that «future
energy» — at least
through the next couple of decades — is largely the same as current
energy, with gains in efficiency and growth in adoption of renewable
sources and nuclear power still not substantially blunting growth in the combustion of fossil
fuels.
The two are inextricably linked
through the fact that our main
source of
energy is fossil
fuels.
Through various life cycle assessment studies (Searchinger et al, 2008; DeCicco et al, 2016) performed on annual bioenergy crops such as corn, it has been shown that they are not much better than fossil
fuel energy sources in terms of climate and
energy impacts.
When the fossil
fuel sources of these environmental impacts are made to pay the true cost of the pollution created,
through mandated updated technological fixes such as improved and more efficient pollution control, limited coal
sources, and other mediation devices, the true cost of coal will make other
energy sources more viable.
If people use less
energy (
through efficiency and conservation) and shift to lower - carbon
energy sources, demand for high - carbon
energy will decline and it won't be economical to go chasing after unconventional
fuels.
«Electricity from Renewable
Energy and Fossil
Fuels with Carbon Capture and Sequestration», the fourth report in the CEF publication series, examines electricity generation
through fossil
fuel combustion with CO2 capture and sequestration («fossil / CCS»)- a process that removes as much carbon as possible from major emissions
sources such as power plants, and stores it in deep geological formations.
We will continue to reduce our greenhouse gas emissions
through innovation and technology breakthroughs, and work with other countries to help them access and use fossil
fuels more cleanly and efficiently and deploy renewable and other clean
energy sources, given the importance of
energy access and security in many nationally determined contributions.
With a carbon price, some fossil
fuels would continue to be extracted because it would still be cost - effective to do so: the market would decide efficiently which
energy sources to use, where
energy can be saved
through energy efficiency improvements, and which fossil
fuels to leave in the ground.
But let's not forget the most CO2 - intensive fossil
fuels (coal, tar sands) do still deserve the highest priority — and are hardest hit economically
through proper understanding of carbon bubble fossil overinvestment and rising competition from renewable
energy sources.]
Table 5 — 2 by Earth Policy Institute with existing fossil
fuel and nuclear capacity from «Existing Capacity by
Energy Source, 2007,» and «Planned Nameplate Capacity Additions from New Generators, by
Energy Source, 2008
through 2012,» in DOE, op.
Particularly since we have a climate change bill making its way
through Congress that will, at long last, if all goes well, put a price on carbon emissions — thereby giving low - carbon
energy sources what they desperately need, which is a fighting chance to compete with fossil
fuels on something resembling a level playing field.
