Often, the only thing people think they know about renewable energy is that it is “too expensive” or “unrealistic”. Well, did you know what people said about the very first automobiles? They said pretty much the same thing about those. Cars were not believed to be able to compete with horse power, since the very first cars were both slow, expensive, and difficult to use and maintain.
So how did cars become so immensely successful? Well, some entrepreneurs - notably Henry Ford - realized the potential of the concept, and solved some of the technical problems. Then, a mass market suddenly opened.
If we look at such things as photovoltaic cells, it is pretty much the same thing: they are now moving from the stage of being expensive novelties to reaching a mass market. Cheap solar panels are now a reality, due to intensive research and development.
For instance, one company now manufactures solar panels by spray-painting a semiconducting layer on to a roll of plastic film. These solar cells will be so cheap that they can directly compete with coal-generated electricity.
This also means that solar panels for home use can now be a very cost-effective investment for the average home owner. Visit www.sunwindnow.com to learn more about renewable energy for the future.
Indeed, the only future we have is a society based on renewable energy. The global warming has to be dealt with, or we will be faced with devastating global effects. Therefore, we need to phase out the use of fossil fuels and replace those with renewable energy sources.
