HOW TO REPLACE FOSSIL FUELS ? THAT IS THE QUESTION
So much of climate change and global warming and consequent pollution
and destruction of habitat and food supplies is tied up with the use
of
fossil fuels and the unthinking use of hydro power that nearly every
aspect of sustainability involves the derivation and use of fuel and
power,
Fossil fuels produce carbon dioxide when burnt. Continued use of fossil
fuels will only increase the problems of global warming and consequent
climate change. It is absolutely essential to drastically reduce the
use
of fossil fuels if any other efforts to create sustainable development
are to succeed.
The reduction in the burning of fossil fuels is the first priority
of
any sustainable development. Fortunately there are in fact several
alterative sources of heat and power ? all of them free for ever
? which
are waiting to be tapped. The sun, the wind, the waves, the tides,
the
earth and gravity are ambient sources one place or another over the
whole globe. The choice of location for a development need only take
into consideration one or more of these sources to ensure sustainable
heat and power. For existing settlements thought needs to be given
to
how to convey heat and power from sustainable sources.
The need of sustainable power to provide the propulsive force for
transport is also there for the taking in the form of solar, geothermal,
wind and wave produced electricity and hydrogen. These technologies
are
developing apace and are already producing viable results, slowed
only
by the protectionism of old fossil fuel producers and their transport
clients, as demonstrated by the documentary "Who Killed the Electric
Car?".
Nuclear power, once heralded as the power of the future, has still
to
fully develop, with fission having its radiation problems and fusion
still to reach commercial realization, but potentially another source
of
secure energy supply.
