Residents in a part of south Devon are dipping into a pot of funds to pay for 'green' schemes at their homes.
And some have been showing off their energy and cash-saving projects to encourage others to take part.
Over the weekend of 11-12 September 2010, some 13 homes around Totnes opened their doors to visitors to show what can be done to save fuel and conserve resources.
Some have solar panels to generate electricity, some use hot water from deep under the ground while other have complex systems to save rainwater.
In the Totnes area, grants are available to help residents put up photo-voltaic (PV) cells which make electricity while the sun shines.
More than £500,000 is in the pot and many people have already taken advantage of the cash.
Adrian Porter from Transition Towns Totnes says more people can apply for grants and that there is also help for people on low incomes if they want to buy and install solar cells.
The transition streets programme is being extended to 15 parishes around Totnes.
