a photovoltaic cell.
That is why we are backing biomass, photovoltaics and wave and tidal.
For all those reasons, financial support should be given to a wider mix of renewable technologies, such as photovoltaics and solar energy.
Although solar energy should be encouraged, photovoltaic modules contain materials that are at least as harmful to the environment as an electric toothbrush.
Wind, solar energy, photovoltaic energy etc. only account for 5%!
I could show you figures and curves here demonstrating that for both wind energy and photovoltaics this mathematical formula applies.
Photovoltaic cells and solar panels are both being considered, and the position in respect of wind power is being reviewed.
Most houses could supply up to half their internal energy requirements from installed photovoltaics and/or from evacuated-tube solar water heating.
The typical payback period for photovoltaic installations is 50–100 years.
