Seven ways to be green with money

By Jennifer Hill

LONDON (Reuters) - Financial service providers are picking up the "eco" baton and running with it -- meaning consumers can factor environmental concerns into everything from utility tariffs, tax returns and even mortgages.

Here, are seven ways they can do it.

USE GREEN ENERGY

The 14 million households that have never changed their electricity tariff could save money -- and the planet.

They could save more than 1.2 billion pounds between them and reduce carbon dioxide emissions by 20 million tonnes by swapping to the cheapest green tariffs, according to price comparison site moneysupermarket.com.

Website Greenhelpline.com allows people to search environmentally friendly energy tariffs, as well as source local food producers.

Energy from renewable sources is, however, generally more expensive than electricity from non-renewable resources and cost savings are generally only available to those who have never switched provider.

Greenhelpline.com -- which makes a flat rate commission of 40 pounds per energy switch, from which around two pounds is profit -- splits revenues 50/50 with energy providers.
