Dear Editors,

Cheap and available technologies that save money and can reduce carbon emissions to zero already exist.

Instead of using fossil fuels, we can convert vehicles to compressed air or even water electrolysis propulsion. [1][2]

Factories, buildings and houses can stop using fossil fuels for heating and electricity and convert to take advantage of U.K.’s huge geothermal potential. [3]

These technologies are safe, cost-effective and available for sale.
