they can coerce the government to destroy its economy from within.
The idea that addressing climate change has a negative impact on economies is another of example of the climate denial industry making claims that are totally and utterly wrong. I know they (understandably) hate evidence, but if they were to make an exception and actually consider reality, just for a change, they would see that it is actually clear that governments are actually destroying their economies by sticking with the (heavily subsidised, in the case of the US) 19th century carbon-based economic model.
Developments in clean power generation mean that many technologies - wind, solar, tidal etc - are already near/at price parity with old style generators. This despite the irony that the greater the success of renewables, the cheaper carbon-based alternatives become as reduced demand pushes down prices. Fortunately, clean energy prices continue to fall as they benefit from R&D and economies of scale.
Another economic benefit of clean energy production in a time of high unemployment is that it
creates more jobs than the old style carbon-based generation it replaces.
The developed economy that has gone furthest and fastest down the road to addressing climate change is also the most consistently successful economy of the last 70 years: Germany.
In Germany, they continue to subsidise clean power production and consequently have one the cleanest electricity generation industries in the world. Far from the German economy suffering from increased electricity prices, it is actually
benefiting from prices that have plummeted so far, the old style generators are petitioning the government to introduce price controls to stop prices falling further. Even paying the subsidy, electricity in Germany costs substantially LESS now than they did before the clean up.
One thing the climate change denial industry has right is that lower power costs are generally better for an economy. They're just completely wrong about how economies can achieve those lower costs.
