The cost of supporting the production of renewable energy seems eye-watering. This column argues, however, that the alternative of a future energy system lacking the benefits of low-cost zero-carbon technologies is even more costly.

Concentrated solar power generation in Northern African and Middle Eastern deserts could potentially supply up to 20% of European power demand. This column evaluates the technological, economic, and political feasibility of this idea. Although concentrated solar power is a proven technology that can work at scale, it is currently four or five times more expensive than fossil fuels. Concentrated solar power could play an important role in Europe’s energy mix after 2050, but only if geo-political challenges can be overcome.

This column explains how US tax policies have induced greater investment in renewable energy production and an electricity grid unable to harness it. It argues for a tax code that offers financial incentives to make new grid investments, lest the US find itself with a power grid that can't transport green electricity to the nation's growth centres – the ultimate bridge to nowhere.
