10 free ways to cut carbon emissions

I think that global warming is a reality, but there is still doubt regarding whether it's a natural phenomenon. If it is it will go away, probably not in my lifetime, but it's part of the Earth's natural cycle. If it's man-made, we should do something about it.
The whole argument about global warming and carbon emissions misses the point.
The major cause of both of these is the burning of fossil fuels. The Earth is a finite size and fossil fuels only occur in the crust, which is a thin layer near the surface. The crust occupies less than 1% of the total volume of the planet (see Wikipedia).
The supply of fossil fuels is limited, they will run out. It is only a case of when!!
I hear people saying that there's nothing they can do about this, but they are so wrong! There are a number of low cost, or free, things that we can all do to save the planet.

1. Unplug or switch off any electrical appliance you're not using. TV, Stereo, even your phone charger;
2. Stop ironing your clothes, an iron uses more electricity than an old-fashioned 2 bar electric fire, 2 units an hour;
3. Fill your dishwasher and washing machine. Avoid running them partially empty;
4. Fit low energy light bulbs. They can each save around 86 units, that's £8 at current prices, per year. Cheap ones cost less than £2 each and even an expensive one will pay for itself in less than a year and go on saving for up to 15 years;
5. Turn your central heating down 1 degree C (2 degrees Fahrenheit), that can save 10% off your heating bill;
6. Use your microwave less often, for example allow time for frozen food to defrost at room temperature;
7. Don't heat an empty oven, try to fill it with food;
8. Don't accelerate so hard and anticipate when you'll need to slow down. Contrary to popular belief acceleration uses more petrol than driving at a steady speed. Driving a couple of mph slower will also help;
9. Reverse your car when you stop, not when you start. A cold engine uses more fuel than a hot one and reverse gear is the lowest gear in most vehicles. Reversing with a cold engine can increase consumption to around 2mpg, so it doesn't take much to make a difference;
10. Empty your car, don't drive round with unnecessary heavy items in it. It takes fuel to move every pound, less weight = less fuel;

Ok one of these isn't free, but it will very quickly pay for itself.
