There is an essential need to get children on side to influence the future use of energy. The effects of climate change are gaining pace and our legacy to the next generation looks alarming. We need our children will need to hit the ground running to have measurable and immediate effect on the use of energy. Educational curriculum in renewable energy must be further reinforced to ensure this happens.
Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, electrical, or other forms.
According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form.
We can it easier for children to understand the situation by emphasising the significant difference between conventional energy and renewable energy. Energy basically falls into two groups; hot energy and cold energy.
Hot energy
The Hot group involves the use of Heat to convert a fuel into energy in power stations. The fuel used; coal, oil or nuclear is Hauled great distances – also using more fuel in the transportation process. The by-product of the hot energy group is Hazardous waste in the form of Hydrocarbons, ash and spent nuclear fuel. History will recall the headache we are handing to future generations.
Hot energy summary:
•   heat
•   hauled
•   hydrocarbons
•   hazardous
Cold energy
The Cold green energy group. Cold, as there is no induced heat source used (Solar and geothermal are natural sources). Clean because there are no emissions, Continuing – as long as the planet exists and Climate friendly because there is no fuel excavated or waste product to be disposed. In this group is solar, wind, tide and wave energy. They are clean, producing no gasses from combustion and no waste heat. (apart from the small amount occurring in the generator itself).
Hydroelectric power also falls into the cold group, but we have excluded it as there is some inevitable environmental damage in the production of dams. Similarly geothermal is a green form of energy and should be in the cold list, despite involving heat, as it has a continuing source of energy – as long as Earth exists!
Cold energy summary:
•   cold
•   clean
•   continuing source
•   climate friendly
In ten years the current negative effects on the climate will have progressed significantly. Politicians and pressure groups have a huge task to convince, let alone convert the population. Progress will inevitably be ponderously slow. OK it may rain a little more and temperatures are perhaps out of seasonable kilter but do we really need to worry?
As the lights are still on, and there’s fuel at the petrol station, ambivalence is set to prevail. We need a severe shortage to focus the attention. Price rises merely isolate the lower paid. The real saviours of the planet may be yet to hit the streets. If we are to achieve the quantum leap to the significant use of renewable energy, time has to be invested in educating children on the full implications of climate change. Their enthusiasm, untainted by our old ways will have a huge benefit in the rate of change towards renewable energy.
A central theme of the latest educational thinking is the integration of subject areas. Renewable energy can have no better application. Energy is a highly practical example where topics interlace many areas of the National Curriculum. Maths, English, science, geography and history all play a part in building a child’s essential knowledge bank in the cause and effects of climate change and green energy. Ideally, learning seen by children to be fun holds their attention and greatly improves the learning curve. The use of educational games to support green energy education will help feed their interest and imagination more than can be achieved by text books alone.
There is also the benefit of the child’s influence and enthusiasm at home in the immediate future. How often are we corrected by our children on issues they are learning at school? The eagerness of the young can be very infectious and a great way to prick the conscience. And despite the growth in awareness and renewable energy schemes that now exist we certainly have a long way to go. We need to make the choice between hot and cold, vastly more focused.
