Often, the debate is presented as if the only question is how high, and how fast does the carbon price need to climb in order to substitute
existing fossil fuel technologies with clean energy technologies, whilst also maintaining economic growth.
And the existing market size for clean energy technologies, including CCS, is small relative to that of
the existing fossil fuel technologies.
Not exact matches
Undertaken by University of Adelaide in collaboration with CSIRO, the research could make viable a process that has enormous potential to replace
fossil fuels and continue to use
existing carbon - based
fuel technologies without increasing atmospheric CO2.
It is also clear, Ban Ki - moon says, that the
technologies already
exist for the world to turn its back on
fossil fuels and cut emissions of greenhouse gases to a safe level.
Our concentrating solar power (CSP)
technology exists to produce clean energy, address climate change, improve air quality and reduce dependence on
fossil fuels.
Fortunately, the relative added costs of today's renewable
technologies are quite reasonable, especially if one factors in the subsidies that
exist for
fossil fuels and if we price carbon commensurate with the costs of its environmental damage.
We need to do a «full court press» to switch from
fossil fuels and nuclear (which also releases heat into water on a large scale, and supports nuclear military programs), using
existing and near - commercialization battery, solar and wind
technology, and design systems to cost - effectively convert the
existing 600 - million - plus vehicle fleet rather than waiting for replacement.
Renewable
technologies already
exist (not hypothetically) that can produce electricity at rates that are competitive with the subsidized rates we pay for nuclear and
fossil fuel generated electricity.
Immediately repeal
existing tax breaks for
fossil fuel exploration and production, and halt efforts to extend and expand tax credits for unconventional
fossil fuel production
technologies, like carbon capture and storage and enhanced oil recovery.
Technology policy can make clean energy cheaper, but not necessarily cheaper than
fossil fuel alternatives, particularly
existing coal power plants whose capital costs are already sunk.
Most of the
existing fossil fuel power
technologies could operate quite well off «renewable»
fuels, with minor adjustments:
Uh, I'm not claiming
fossil fuels, or any
existing technology will always be around while any newer energy
technology is just a fad.
If these limits did not
exist and there really could be a tipping point beyond which these green
technologies would mercilessly sweep aside
fossil fuels for good, I'd be all for it.
As the agencies acknowledge, no commercially - proven
technologies exist to filter out or capture carbon dioxide (CO2) emissions from
fossil fuel - powered vehicles.
When it comes to providing new electricity to the developing world, Jigar Shah has been making the case that all the renewable
technology we need already
exists and can be deployed more cheaply than
fossil fuels.
As a first step, we should dismantle the web of policies that overwhelmingly favors
fossil -
fuel production and use and actively discriminates against new
technologies and practices that would reduce harmful emissions... The second step is to institute federal, state, and local policies that reverse the disincentives created by the
existing policy structure and force users to pay the costs of extracting, transporting, and burning
fossil fuels.
Nuclear,
fossil fuel, and concentrated solar power plants require methods for cooling plant equipment and / or cooling steam; this is often accomplished by cycling through large quantities of water, although
technologies for «dry cooling»
exist as well.
Our concentrating solar power (CSP)
technology exists to produce clean energy, address climate change, improve air quality and reduce dependence on
fossil fuels.
It's about
technology and manufacturing making the extraction of
Fossil Fuels economically not viable, and thereby reducing, perhaps to zero, the value of those FF resources «owned» or «leased» by
existing powerful actors.
But if
existing zero - carbon
technologies can not affordably be scaled up to meet current and projected global energy needs, how likely is it that
technologies either not yet invented or as yet prohibitively expensive can affordably replace the world's
fossil -
fuel infrastructure?
