On energy and global warming
In his book The Carbon Crunch and in print media, Dieter Helm has criticised efforts to reduce greenhouse gas emissions through current regulation and government intervention, and the deployment of renewable sources of energy, particularly wind power.
He recommends establishing a carbon tax and carbon border tax, increased funding for research and development, and an increased use of gas for electricity generation to substitute coal.
