The sun shines free of charge
The sun is available to us as an inexhaustible energy source. It supplies more energy every day than we could in theory use throughout the world. Luckily, the environmentally friendly electricity from solar cells can increasingly be used for common articles of daily use.
The interest in alternative energies continues to rise rapidly in light of dwindling resources with increasing prices. The unlimited supply of solar energy is cost-effective, does not produce harmful CO2, and therefore offers double the conservation of Mother Earth's resources. Solar power is also the only type of energy that can be generated locally anywhere in the world. In terms of service capacity, humanity has now only scratched the surface of possibilities.
In private households, solar energy is chiefly used to heat water and generate heat. Many homeowners already have solar systems installed on their roof. According to estimates of the solar industry, if all suitable roof areas in Germany were to be used, approx. 30 per cent of Germany's demand for electricity could be covered.
But even people that cannot call extensive solar systems their own can still profit from the power of the sun. Many household appliances can now be operated with solar energy. It started once upon a time with calculators and today is available even for refrigerators, stoves, or ovens. The opportunities for environmental protection and savings options grow particularly in this area.
For a long time, solar-powered devices had a reputation of being expensive. Today, these small appliances are not much more expensive than others – and they also save energy. Up to 25 per cent of the electricity consumption of a household can be reduced with the purchase and use of energy-saving household appliances.
Whether it's radios, clocks, outdoor lighting, or scales: high-quality solar devices store the electricity absorbed during the day in condensers, which is why they work even without rechargeable batteries. Modern solar cells charge themselves with energy even in low light conditions or under artificial light and can easily bridge times without light. Power cords, rechargeable batteries, and batteries are therefore a thing of the past. This active contribution to environmental protection significantly reduces piles of rubbish and hazardous waste. That the wallet is protected as well is an added – and very pleasant – side effect.
