Countries all over the world are attempting to address the problem of global warming and are switching to alternative energy sources. These are encouraging trends, and the US should take note and consider following the examples of other nations.
There is no one answer to the energy crisis we face. Hydrogen alone is not the answer. Neither is ethanol, wind power, solar energy or cogeneration alone. There is no magic bullet, no one miraculous technology that will end our dependence on nonrenewable energy.
Rather, the solution to the carbon problem lies in quickly developing a diverse energy portfolio and a proactive policy on the part of the federal government. The US must utilize all energy options available, and can do this by following state and international examples of policies that reduce barriers to entry for new technologies. Development of infrastructure, lowering subsidies on fossil fuels, and reducing tariffs on clean energy from other countries are all actions that the US should pursue, in addition to developing incentives for more corporate investment in alternative energy. Only if there is a cooperative public-private effort to encourage renewable power will the US be able to move quickly enough to a sustainable, carbon-free economy.
To prevent the most serious consequences of climate change, many of which have been outlined in earlier chapters, the US and the international community need to take dramatic steps within the next decade to reduce carbon emissions. This may sound like a daunting task, but the corporate investment, state initiatives and international leadership that have begun indicate what is possible - but they are only beginnings. More work must be done to develop alternative energy sources and to improve energy efficiency, and much of that work must be encouraged, promoted, and even led by the federal government. It is time for Congress and the White House to take responsibility and show leadership for our future.
The US has accomplished extraordinary feats before and we can do it again. We can reduce our greenhouse gas emissions, we can stabilize atmospheric CO2 concentrations, and we can avoid the most devastating consequences of climate change. We can increase corporate investment, we can produce effective and long-lasting government policies, and we can work with our international partners on this global problem. But, for environmental, moral, stewardship and long-term economic reasons, we all need to make the commitment and we need to make it now. If we rise to this occasion, we will make the world more stable, secure and prosperous, and future generations will appreciate that we had the wisdom and moral courage to meet the climate challenge.
