Common questions and misconceptions about solutions to climate change:
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.
