Stephen Crivillaro - Power Plant Emissions Stephen Crivillaro majored in Labor Studies at Queens College in New York. After earning his Bachelor's degree he moved into the field of renewable energy, where he became a green energy consultant, and did that for a number of years. Renewable energy is one of the most important issues facing the world today, says Stephen Crivillaro. There is a finite source of fossil fuels and the world is quickly depleting it. Renewable, sustainable energy technologies, however, are clean sources of energy that have the potential for virtually infinite use, and they are much safer for the environment because they do not emit greenhouse gases, and reduce emissions into the atmosphere. Moreover, by harnessing renewable energy sources like solar and wind power, the United States can reduce its dependence on fossil fuels that are imported from foreign sources. Renewable energy, says Stephen Crivillaro, is an umbrella term that refers to wind, solar, geothermal, hydroelectric, and biomass energies. Each of these can provide many benefits to society and the health of its people, its economy, and the world's climate. He says that global warming is becoming a bigger issue with each passing day, and that the production of electricity accounts for more than a third of the global warming emissions from the United States. And most of that, he says, is generated by coal-fired power plants. These produce about one quarter of the total global warming emissions in the U.S. The second major producer is power plants fired by natural gas, but these account for just six percent of the total emissions. Renewable energy sources, on the other hand, produce next to nothing in global warming emissions. Stephen Crivillaro is convinced that by increasing the supply of renewable energy, the United States could replace carbon-intensive energy sources and greatly reduce the amount of global warming emissions produced by the United States annually. Boosting our renewable energy standards by twenty five percent would lower CO2 emissions from power plants by 277 million metric tons, and he says that we should be aiming for an even greater percentage, although he also says we have to take this one step at a time. The cleanest of the renewable or sustainable energy sources are wind, solar, and hydroelectric systems. These generate virtually no air pollution emissions. Other renewable sources like geothermal and biomass, says Stephen Crivillaro, do generate some air pollutants, but what they produce is next to nothing compared to fossil fuel emissions.
