Renewable energy has drawbacks and environmental consequences

Renewable energy sources — wind, wave, solar, and the like — are generally the preferred energy sources of environmentalists. At the same time, there is no way to produce energy without some sort of environmental impact, and the more people you need energy for the greater the impact will be.

Some examples of environmental impacts from renewable energy:

• Mesmerised brown crabs ‘attracted to’ undersea cables
• How do tides and turbines affect sealife? Fundy study hopes to find out

Nonetheless, unintended side effects of renewable energy sometimes lead environmentalists to oppose it. In my view, they are missing how every energy source will have drawbacks and the question is how they relate to the drawbacks from alternatives, chiefly fossil fuels. Environmentalists can be too easily inclined to become perpetual and reflexive critics, always emphasizing the problems with any course of action and effectively acting as a blockage to any action.
