Does your property have a water course crossing it, a stream or river. Do you own an old water mill? Water turbines/ hydroelectric turbines are the ideal method to provide reliable renewable energy on a long term basis. The available power at your proposed site is simple to calculate using this equation:
Power (watts) = Head (m) x Flow (litres/sec) x 9.81 (gravitational constant ‘g’)
A typical efficiency of water to wire is around 70%, you should therefore multiply the result by 0.7 giving the actual amount of electricity that you could expect from your proposed hydro site. Looking at your power consumption in "Solar panel costing.xls" a 3KW turbine should be adequate. It costs about £1500 so it will pay back in just over a year. Background information.

I have not worked up a calculation but I think most of the information can be found www.essentialspark.co.uk. Please upload the calculation to the site if you manage to get round to it quinetic.

The wind turbines mentioned in the latest ExcelCalc post were small roof mounted turbines but what about the large turbined that can be placed on top of large buildings or mountains or in the open plains as in the US and promoted recently by T. Boone Pickens and does Mr. Pickens have an interest in those companies or are his motives altruistic?:unsure:
