Good tip!
However, I feel that for the sake of bystanders, I should clarify one or two teensie errors as well............
Solar thermal, if carefully chosen, and installed economically is probably the most cost-effective renewable energy for most people..........
Solar PV, although expensive is incredibly reliable, will probably be producing power for 50 years, is entirely predictable, and can most certainly supply a home's complete needs..........
Then probably the silliest comment of all - that about "wind" - for most homes in the UK, it is not appropriate (in simple terms, planners won't allow sufficiently tall masts to get turbines up above the turbulence in most residential areas), BUT there is no escaping the fact that a properly sited turbine, atop a suitable tower will reliably and economically produce gobbets of power.......... apply the economies of scale in larger turbines, the sums become incredibly attractive, to the extent that without a grant or subsidy in sight, anyone who owns a suitable site would be bats not to........
And last but not least, the often committed error of equating "money saved" with greenness - they are not in any way linked..........if you swap one fossil fuel for another, as like as not you may save money, but you may in fact increase emissions.........
