But with peak oil and possibly peak gas around the corner, it should be; there are lots of ways to make electricity but how will we heat our homes?
Now with Government incentives and interest free loans, it is getting interesting. The City of Toronto is converting its swimming pools to solar, and Wal-Mart is testing a system on one of its big boxes in the Toronto area. The Provincal government announced the goal of having 100,000 solar electric or thermal systems installed across the province. A lot of older houses (and some new ones with radiant floors) are heated hydronically, and these are a natural for conversion; it can provide all of the heat some of the time and in really cold weather it certainly cuts down the fossil fuel needed. The hot water can also be run through coils to adapt to hot air heating systems.
System prices are dropping quickly now that evacuated tubes are made in China; at a trade show recently we saw a package unit with evacuated tubes, a strorage tank and controls for under six thousand dollars, about the same as we paid for our high efficiency furnace. ::Toronto Star
