Yes, the United States is in danger of falling behind in renewable energy. We already rely heavily on non-renewable sources of energy, and with the new elected officials taking office, the United States will continue that dependency. In order to stay ahead in renewable energy, we need to invest money into it. However, those who control the money will not opt to spend it in that way.
So far, there is renewable energy that works, but there is no evidence that it's better or less expensive than the United States is already using. The United States should stop using other country's crude oil. But spending large amounts of energy on renewable energy is not the answer because it is expensive.
Most of the industrialized countries of Europe have already surpassed the US in renewable energy. The third world countries seem to be more open and willing to adopt green energy. The US government is tainted by the influence of energy companies, some of whom only recently began to open up to the idea of renewable energy.
The United States is not in danger of falling behind in renewable energy, because so called green energy is not as reliable as traditional sources. America has become a leader in oil and gas production--oil and gas is what fuels our economy; not wind or solar. Other countries will find that renewable sources of energy are not as reliable.
