Nowadays, the increase in the price of gas is a phenomenon one cannot consider as erratic. It is an occurrence that infuriates the general public. But one which people have to endure, come in terms with, and tighten their belts for them to be able to tide over the situation. The last two decades or so have seen some of the most unusual spikes in the price of gasoline, and consequently, this results to an increase in the cost of other commodities as well.
But where should you start when teaching renewable energy for kids? A good idea would be starting with defining exactly what renewable energy is. You can suggest they make a list of non-renewable and renewable power sources and build from there. Some examples would be:
Non-Renewable: Oil/Gas, Natural Gas, Coal, Nuclear
Renewable: Solar, Wind, Geothermal, Hydro/Water.
Explain to them how renewable energy comes from natural forces. It is different from fossil fuels as it does not make greenhouse gases or other pollutants. You can further explain how the mass production of electricity using renewable energy sources has only recently become more popular. Some of the reasons why it's becoming more popular include: climate change caused by pollution and fossil fuels are all being used up and becoming more expensive.
A great idea is to teach kids about energy efficiency. Have them make a list of all the powered devices they use for a day such as TV, computer, lights, etc. and for how long, and if possible the wattage of each device. If they can't get the wattage, you can look up the average wattage for each device for demonstration purposes.
Another study was one from the Department of Chemical and Environment Engineering at the University of California, Riverside. The process they have developed was one which combined excess glycerin and excess biomass from biodiesel production to produce flammable pellets for use as an alternative to coal.
Another great idea is show them how installing a solar panel or windmill can generate electricity for their own home. It's not as expensive as you might think. You don't need an expensive commercial solar panel, you can build your own for $100-200 dollars and your kids could even help if they're old enough. The less they take energy for granted, the better.
