Renewable Gas Heating in the UK

http://news.bbc.co.uk/2/hi/science/nature/7862696.stm#top

This article describes a possible new source of fuel that is more eco-friendly than traditional gas heating. By burning waste they can obtain gasses from the process to heat homes. This will save fossil fuels and create a use for the waste in landfills. One of the downsides it mentions is that if this gas leaks it's 20 times more damaging to the enviornment than CO2.

This seems like a very viable solution to me. It would lower heating costs and, overall, be more friendly to the enviornment. However, conclusions about this must take into consideration the part of the article titled "Over-optimistic" warning about the report being more idealistic than is possible to achieve.

I noticed, on a stylistic note, that this article seems to have a slightly different writing style than some other articles I've read. I was thrown off for a moment when it started the regular article by saying "It says." At first I was unsure of what it refered to. It seems strange to me that the writer of a news article wouldn't make himself perfectly clear.
