US based Natural Resources Defence Council and the Alliance for Clean Energy in New York have unveiled a new website to help businesses and consumers directly purchase renewable energy certificates (RECs).

The website, Green Power NYC, enables users in New York to choose the energy providers and the type of clean power.

Once users make their selection, they sign up to the scheme and get one cent to 2.5 cents per kWh added to the electricity bill. In return they get renewable energy credits tied directly to the green energy produced by participating companies.

The programme is designed to help reduce carbon emissions, increase economic development in the clean energy sector and discourage construction of new fossil fuel-based power plants.

The renewable sources of electricity for NYC include biomass, wind energy, solar energy and solid waste, each of which account for less than 1% of the total, according to the authorities.
