Fossil fuels, the source of much of our energy, are formed under intense pressure and heat over millions of years from the buried remains of plants and animals. By burning these fossil fuels to release heat from the chemical energy they contain, steam can be raised in a power station boiler. The heat and pressure energy in the steam is turned into work in a turbine, which drives a generator to produce electricity.
However, by burning fossil fuels we are releasing carbon dioxide (CO2) into the atmosphere faster than plants can absorb it. CO2 is a major contributor to the greenhouse effect; as more fuels are burnt, the atmospheric concentration of CO2 increases, causing the average global temperature to rise. Climate change affects the distribution of climatic regions, sea level changes and ultimately, the planet’s ability to support human communities. Burning fossil fuels also contributes to acid rain, which is implicated in the loss of wildlife in lakes and rivers, the reduction of land fertility and the destruction of trees.
However, there are certain steps we can take to start on our way to reducing our energy consumption at home and in school. Energy surveys are a great way to identify the amount of energy used in the school, and can highlight areas where changes and improvements can be made. There are many simple low and no-cost tips that can be carried out to increase efficient use of energy.
Energy Saving Tips
Energy is fundamental to the way we live our life today. Electricity is an amazing resource and should be used efficiently both at home and in school. Here are a few tips to help you use energy more efficiently and save money too;
Turn Off the Lights!
Don't leave lights on when no-one is in the room. In school put stickers on light switches to remind everyone to turn off the lights at the end of class.
Use energy efficient light bulbs (compact fluorescent light bulbs). These bulbs use ¼ of electricity as normal light bulbs and last up to 12 times longer!
Turn Off Appliances!
Turn off your TV, stereo, playstation, computer, washing machine, DVD and other appliances when they are not in use. Leaving appliances on stand-by uses energy so remember to switch them off.
Put stickers on photocopiers, computers and other appliances in school to remind everyone to turn them off.
Turn Down the Heat!
Turning the thermostat down by 1°C can reduce your heating bills by 10%.
Remember to turn off radiators in school after 12 noon unless it is an exceptionally cold day.
Close your curtains at dusk as curtains block cold air coming in.
Check all windows and doors to see where draughts are coming in. If you identify draughts get your parents or teachers to seal them up. Why don't you try and make a draught excluder using old clothes!
Turn Off the Taps!
A dripping hot water tap wastes energy and in one week wastes enough hot water to fill half a bath, so fix leaking taps and make sure they're fully turned off!
Turn off taps - wasting water wastes electricity as a huge amount of electricity is used daily in supplying water and cleaning it after use.
