Isn't alternative energy too expensive? Can it really solve our energy needs?
To fully answer this question, you need to compare both short-term and long-term costs. In the short-term, today's alternative energy producers are often more expensive than traditional energy sources. However, when long-term costs such as pollution, global warming, and quality of life are factored in, alternative energy is by far more cost effective. Although it is hard to change, when faced with challenges, America produces innovative solutions that lead the world.
America's national parks were once a new innovation. One hundred years ago national parks were considered by some to be expensive and controversial. Now they are recognized the world over as one of America's best ideas, a priceless legacy that protects our natural and cultural heritage for generations to come.
