Any serious discussion of the issue of energy independence and global warming must recognize the extreme complexity of the topic, as well as the wide variety of views of the problem and the remedies. And since energy use is such an important issue, not only for humanity, but also for us as a nation, it calls for a major, multifaceted, comprehensive approach.
Even if the body politic were united on the need, which it is not, there are so many interests and factors involved that it will be a major challenge to arrive at a rational energy policy which will effectively address the problem and move us towards true energy independence, a secure economic future, and a cleaner environment, while preserving our planet.
Even for those who question whether human activity has caused recent global warming, it makes sense to develop new sources of energy that do not drain our national resources by importing oil or protecting our access to oil through military force, at the same time providing cheaper and cleaner energy. Since fossil fuels are finite resources, we should also be actively searching for new sources of energy before they are exhausted or their cost becomes prohibitive.
It also makes sense to foster the development of new technologies that will make this independence possible, while employing thousands of Americans at high skilled jobs. If we wait for other countries to develop these new energy systems, and we are already behind Germany, Japan and Denmark, we will lose a great economic opportunity and will end up importing technologies instead of developing our own and exporting them. Instead of importing oil or liquified natural gas, we will continue to out source good manufacturing jobs and import costly equipment to generate electricity.
Alternatives Are Not Without Consequences
Recent initiatives to increase the production of corn-based ethanol to replace imported oil, however, are counterproductive, since its production consumes as much energy as it provides, some of it from fossil fuels, and it has already led to higher prices for corn and other foods. Therefore, while an increased reliance on coal and ethanol would promote energy independence, neither would reduce harmful carbon emissions.
Other bio-fuels might be more efficient than ethanol, thereby saving energy while creating new jobs. Nuclear energy would provide power without emissions and increase energy independence, but any new plants would be very expensive and no one has solved the problem of nuclear waste disposal.
This leads to the potential of alternative, renewable sources, like solar, wind and ocean wave-produced energy. Though the last is still unproved, it does show promise and is currently being tested in several coastal areas. Wind turbines and solar installations currently require substantial investments, but more efficient systems are being developed and as the market expands, costs will be driven down. Here is where government subsidies, or tax deductions, could play a major role by promoting the development of new technology, creating new jobs and lowering equipment and installation costs.
While solar and wind power are intermittent or not available in all areas, they are providing clean, renewable energy at increasingly competitive prices. Public institutions and corporations have recognized the opportunity to reduce energy costs and are already installing solar panels and wind turbines to replace traditional sources of power. In order to make wind and solar more viable, improved batteries or storage systems need to be developed, as well as more efficient transmission arrangements between these remote sources and the markets where the energy is consumed. To make this happen, cooperation between government agencies and the private sector is crucial.
Wind and solar systems also have the potential to create more jobs than relying on capital-intensive industries like coal, oil, natural gas and nuclear power. Since all of these, including ethanol, also require large amounts of water, they increase pressure on an increasingly scare resource, vital to human survival and a major source of conflict throughout the world.
In California, it is estimated that 20% of the energy is used to pump water, mainly to supply the thirst of Central Valley agriculture and Southern California development. Using non-renewable sources seems counterintuitive in sunny California, in as much as the power to move water over mountains increases the state’s energy budget and carbon footprint.
In other parts of the world, however, millions lack potable water, often because of a lack of electricity. Every year more people are displaced because of a lack of potable water than from war and thousands of children die every day from diseases due to tainted water. Wind and solar power, however, have been harnessed in some of these remote areas to pump water from the ground or run water purification and desalination plants.
Solar Doesn't Always Mean Photovoltaics
The sun not only enhances the quality of life by providing electric power for these communities, but in some areas of Latin America, Asia and Africa, solar box cookers have replaced wood or cow dung as fuel for domestic cooking. Thanks to the efforts of various NGOs, these basic devices have slowed deforestation, reduced the time and energy expended in collecting fuel, mainly by women, and decreased the unhealthy fumes they breathe, while improving the nutritional value of food through a gradual cooking process.
Since we are such intensive users of energy, buying more appliances with shorter life spans, living in larger homes, commuting longer distances and consuming goods from distant lands, none of the above will come close to solving our energy problems, especially as our population grows and other countries raise their standard of living.
What we need, therefore, is a comprehensive program that emphasizes conservation, reduces waste, encourages the development of new technologies and builds a new more efficient infrastructure. It is estimated that conservation alone would not only reduce operating costs for homes and businesses, but also eliminate the need to construct any new coal-burning energy plants.
By developing a more efficient energy infrastructure and promoting conservation, we can slow the rate of increase in our energy consumption, and combined with the development of renewable sources of energy, reduce our dependency on imported or native fossil fuels, foster a more stable energy future, create jobs and reduce harmful carbon emissions.
Given the energy costs and the emissions released to transport our food and consumer goods, this national energy policy should also emphasize buying locally, supporting local producers and workers and encouraging community development. Since it is estimated that much of our food travels an average of 1500 miles to reach us, consuming local goods would lower their cost, reduce energy consumption and emissions and support local growers.
Trains, Planes and Automobiles -- Nothing Can Be Left Off the List
Clearly a comprehensive national energy policy must include the development of more efficient and cleaner cars and trucks, as well as more accessible public transit. Even if we manage to produce and sell clean cars running on electricity or bio-fuels, however, urban sprawl and liberal land use policies will continue to foster energy waste, not to mention stress levels and road rage. Currently the focus is on making our vehicles more fuel-efficient, not on redesigning our cities to reduce commute times or lessen the fuels consumed and emissions released.
Green building is catching on, encouraged by government mandates as well as promising reduced energy costs over the lifetime of the structure. But will Americans be willing to accept changes in lifestyles or be willing to invest in more energy efficient, but also more expensive, cars, homes and appliances?
