Earth’s growing population is consuming its resources to quickly, experts say. Scientists have
emphasized the need to develop new sources of energy, while at the same time protecting the
environment. Economists predict that oil prices will likely continue t o rise, and consumers, especiallylarge corporations, retailers, hospitals, and schools will be looking for cheaper sources of energy, suchas solar power. The sun gives off more energy in one hour than the entire world population consumersin one year. However, the challenge for inventors is to convert solar power into useful forms, and tostore it inexpensively.
