This is most likely to be achievable with the use of photovoltaic panels, primarily on roofs as a later installation.
Light can be used in the facade by the incorporation of photovoltaic cells.
And so the energy demand of buildings needs to be reduced and the reduced quantity of energy can be provided from renewable sources such as wind, tide, and photovoltaic cells.
Statistical studies of learning curves for the costs of photovoltaic modules have shown costs to decline by 20 per cent for each doubling of cumulative production.
The growth in energy use will unquestionably involve renewables, hydrogen, photovoltaics, biomass and the exploitation of wind and waves.
Indeed, the proposal contains a number of derogations, particularly as concerns photovoltaic panels.
Research on those matters suggests, for example, that photovoltaic panels have an energy payback time of two years or a little more.
The typical payback period for photovoltaic installations is 50–100 years.
Most houses could supply up to half their internal energy requirements from installed photovoltaics and/or from evacuated-tube solar water heating.
Photovoltaic cells and solar panels are both being considered, and the position in respect of wind power is being reviewed.
I could show you figures and curves here demonstrating that for both wind energy and photovoltaics this mathematical formula applies.
Wind, solar energy, photovoltaic energy etc. only account for 5%!
Although solar energy should be encouraged, photovoltaic modules contain materials that are at least as harmful to the environment as an electric toothbrush.
For all those reasons, financial support should be given to a wider mix of renewable technologies, such as photovoltaics and solar energy.
That is why we are backing biomass, photovoltaics and wave and tidal.
