Energy use comes in many forms. Of course we are most familiar with electricity, gas, petrol and diesel. Petrol, diesel and gas being fossil fuels, along with coal of course. Use of fossil fuels results in an increase of the greenhouse gas CO2 in our precious atmosphere.
All types of energy come at a cost to the environment. Compared to fossil fuel energy renewable energy is responsible for less CO2 emissions. However, it still has a carbon footprint. Click here to learn more.
Finally there is another source of energy. Our food. This gives us energy. Growing and processing food uses energy.
Food for the humans on the planet, food for our farm animals and our pets. All wild creatures need food too. The food industry also pumps that gas, CO2 into the atmosphere as well. It also adds large quantities of Nitrous Oxide and Methane, both much more powerful greenhouse gases than CO2, but with a much shorter half life. I will explain in due course.
