Solutions myths
Wind
farms are ugly to look at.
Well,
we suppose it comes down to personal aesthetics - beauty being in the eye of the
beholder and such. Personally, we like the look of wind turbines.
But then, when we look at them we see a stable climate, living coral reefs,
polar bears that haven't become extinct, glaciers that haven't melted, costal
cities without flooding, and a source of energy that will safely power millions
of peoples lives without ruining millions of others.
So if you think wind farms are ugly then maybe you just aren't looking close
enough.
Wind farms are too noisy.
See above. We think they are music to our ears. Of course, in
the early days of this pioneering technology, noise was an issue. However, these
days, in reality you can't even really hear them at close distance. From
about 275 metres (900 ft) an operating wind farm makes roughly as much noise as
a refrigerator. In fact, you can stand right under a modern wind turbine
and hold a conversation without even raising your voice.
The wind does not always blow, what then?
Actually, the wind always blows somewhere (particularly off shore and at
heights), so this issue is largely irrelevant with a proper electrical grid to
move power from one place to another. Modern power grids already transmit
electricity over hundreds of kilometres, and cope with significant fluctuations
in both demand and supply.
Of course, it is also a good idea to have a mix of power solutions - including
solar, bioenergy, and hydropower - to balance the strengths and weaknesses of
each source against each other.
Solar power is simply too expensive
"Projections for 2020:
Prices for grid connected PV systems Reduction to 2 euro per Wp"
-- Greenpeace report: Solar
Generation II (pdf)
What does this mean? Solar photovoltaic electricity can compete with
conventional end consumer electricity prices within the decade. In sunny
regions, this breakeven point could be reached even earlier.
The price of photovoltaic systems has fallen by an average of 5 percent per
annum over the last 20 years, and it is expected that this rate of price
decrease can be maintained in the future. That's a considerable price
drop, especially considering that energy costs from conventional fuel sources
are expected to rise (due to fuel costs and more expensive modern power plants).
Furthermore, comparing bulk (power plant) rates is sometimes misleading. Roof
top solar instillations, for example, supply energy directly to the home owner.
Therefore, it's more accurate to evaluate them in terms of costs to the consumer
(retail energy prices as opposed to bulk). And, as experience has shown,
solar turns out to be a profitable investment for homeowners.
Finally, the true costs of fossil fuels are not included in price comparisons.
They include the very real economic costs of climate change, pollution, and
government subsidies - which strongly favour coal, oil, gas and nuclear in many
countries, like the
US
.
Taken together, it turns out that solar is more than competitive.
The "clean coal" fiction
There is also no such thing as clean coal. It is, in fact, the world's
dirtiest fuel. One example - a new "clean" coal plant created
with federal subsidies in Jacksonville, US, will still spew 10 times as much
smog-causing nitrogen oxide as a natural gas generator. It will also release
twice as much carbon dioxide, which contributes to climate change, and
considerable amounts of sulphur dioxide, an ingredient in smog and acid rain.
Obvious oxymorons aside, it is mad folly to replace one environmental disaster
with another. Climate change will be stopped by increased energy efficiency, and
a shift to renewable energy such as wind, solar and biomass. It will not be
solved by taking a step backward to the dirty and dangerous technologies of the
last century.
Shouldn't we be building more nuclear power plants? Aren't they
greenhouse gas free?
Really, we can't understand why anyone (outside of the nuclear industry) thinks
this is a good idea. Nuclear power is the most expensive and most
dangerous means ever devised by humans to boil water. Plus, it still has
all of the same fundamental problems it did ten, twenty and thirty years ago
(risk of nuclear weapons proliferation, the unsolved radioactive waste problem,
plant safety problems, security issues, etc. etc.). It's time to stop
throwing good money after bad.
