We are working on updating our Energy theme. Schools that were awarded the Green Flag for the Litter and Waste theme in 2022 will move directly to the Water theme next, and re-visit the Energy theme at a later stage. This theme looks at the steps which can be taken to reduce energy consumption and raise awareness of climate change issues.
Sustainable Development Goals

In 2019/2020 Green-Schools students saved 29 million units of electricity – That’s enough to boil a kettle 290 million times!

What is Energy?

Science defines energy as the ability to do work.

The sun’s energy is the primary source of energy for all life on Earth. Energy changes form at each step in the chain. Humans and other organisms use energy to survive (grow, change, maintain health, move, and reproduce).

To heat our homes and schools we need an energy source. These energy sources can be categorised as renewable or non-renewable energy. Renewable energy is one that can be easily replenished while non-renewable is one that cannot. Examples of renewable energy include; solar, wind, geothermal, biomass and hydropower.

Fossil Fuels are non-renewable and include; oil, natural gas and coal. These are formed under intense pressure and heat over millions of years from the buried remains of plants and animals. Burning fossil fuels releases energy in the form of heat. In recent decades, humans have been burning more and more fossil fuels to meet the world’s energy demands. Burning fossil fuels 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. Furthermore, by burning fossil fuels to release heat 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.

The good news is, there are simple steps we can take to reduce our energy consumption at home and in school. Many of which are simple low and no-cost actions that can be carried out to increase efficient use of energy and help save you money.

Working on Green-Schools has helped to create awareness about the energy we use in our lives and where this comes from. The children realise that we can all help to save energy-even by taking small steps in our day to day lives and they have also taken this message home!
