We will avoid and reduce unnecessary energy use, and where possible will use renewables.

"In some ways it's cheaper to meet environmental standards by using renewables," he said.

The inference from this model therefore is it costs significantly more to produce the same amount of electricity using renewables.

Already, 80,000 march across Britain and there will be more as our energy supplies are increasingly electrified, whether from using renewables, nuclear power or shale gas.

In addition, a localised power supply, especially if it uses renewables, can provide you with energy security in the face of disruptive events.

Second, there has been enough evidence given today about the necessity for a directive using renewables in heating and cooling.

Politicians talk more about the need to use renewables than those who take the real decisions in this area, that is to say the general public.

If we look at what can be done in industry by trigeneration and by using renewables, it is perfectly possible.

Secondly, every building consuming 40% of our energy today can be transformed into a low-energy building by using renewables, even in a positive-energy building.

In Finland we use renewables mainly in the form of wood, in its various forms, and peat, which has a substantial share of the market.
