Renewable energy sources such as solar, wind, hydro, and geothermal are clean, abundant, and cost-effective.

Renewable Energy is Revolutionizing the Energy Industry

Renewable energy is changing the way we produce and consume energy. It is an increasingly popular and sustainable solution to the challenges of climate change, energy security, and economic growth. Renewable energy sources such as solar, wind, hydro, and geothermal are clean, abundant, and cost-effective.

The United States currently uses more than 140 billion gallons of gasoline and almost 40 billion gallons of diesel fuel annually.

Ethanol and Net Energy

The argument focuses on the energy consumed by the tractors and the farm equipment, the trucks that transport the ethanol to market, and the fertilizer that is made from fossil fuels, as well as the amount of energy required to extract the sugar from corn starch (or cellulosic biomass) and convert it to ethanol.

Renewable energy is renewable because nuclear energy is sustainable for a period of time that is longer than humans need to worry about.

Renewable (sustainable) Energy

The amount of energy that enters the earth’s atmosphere every year through solar radiation is greater than the total energy locked within all of the oil and coal that can be found on earth.

All of California’s electricity can be produced from 200 square miles of sunshine; 128,000 acres of desert land.

Concentrated Solar Power (CSP)

A CSP dish or tower looks like a modern glass sculpture and contributes aesthetically to the landscape. CSP technology has more than one form. Troughs, dishes, and towers are the different forms available today. CSP systems can achieve 30 percent efficiency, or about twice the efficiency of standard photovoltaic cells (2 x .75 = 1.5 kilowatt-hours per square yard per day).

In some applications today, trees are actually being used to remediate soils from toxic contamination.

Renewable Forests

Fully 75% of the U.S. population lives in major urban areas which are generally void of all forests. Yes, there are trees, but the role of forests in the survival and advancement of humans, as well as their potential for future advancements, goes largely unmentioned in this nation.

Along come the politicians, demanding that utility companies buy electricity generated from wind.

Wind Power

Wind engineers are doing a brilliant job developing solutions that have vastly improved the performance of wind turbines and the generators connected directly to the turbines; as well as in understanding the behavior and availability of wind resources. But it is time for Engineers to turn their creative efforts toward solving the problem of wind energy’s intermittency.

Seventy-five kilowatt-hours per day is a lot of electricity for a single-family home.

Solar Energy Potential

You do not need advanced math skills to follow and perform the arithmetic examples shown below. Anyone who can balance a checkbook or calculate the total square feet of floor space in his or her home, and understand why an area measuring 10 yards by 10 yards equals 100 square yards, can perform the following arithmetic examples and prove that American energy independence could be achieved with solar energy alone.

The deep Switchgrass root system could store tons of atmospheric carbon – removing the cause of global warming.


The Biofuels Feedstock Development Program (BFDP) at DOE’s Oak Ridge National Laboratory (ORNL), has assembled a team of scientists ranging from economists and energy analysts to plant physiologists and geneticists to lay the groundwork for this new source of renewable energy. Included are researchers at universities, other national laboratories, and agricultural research stations around the nation.

Cellulosic ethanol is made from the stems, leaves, stalks, and trunks of plants, none of which is used for human food production.

Cellulosic Ethanol

As more and more corn grain is diverted to make ethanol, some groups have become concerned about food shortages. Dr. Bruce Dale, Michigan Agricultural Experiment Station (MAES) chemical engineering and materials science researcher, has used life cycle analysis tools, which include agricultural data and computer modeling, to study the sustainability of producing biofuels – fuels such as ethanol and biodiesel that are made from renewable resources.
