New York Times Article Review SEE below instructiuon - Essay Example In case the price tag is approved by Washington, the carbon content of fuel will become as important as the fuel cost and may even define the fuel cost. The result of this policy will be the competitive capacity of alternative energies, such as wind, sunlight, uranium, corn stalks and trash or natural gas. It would also be possible to start using the so called â€Å"carbon-negative† fuels, taking carbon dioxide out of the atmosphere. The Congress should introduce a special tax or a cap-of-trade system for industries producing fuels. The estimations show that at $50 per metric ton the cost of a kilowatt-hour produced by coal will go from about 5.7 cents to 10 cents. When carbon dioxide costs $25 a ton, wind power will become competitive. Solar power is very expensive now, but the cap-of-trade system making coal fuel equal or even higher in price, solar power gets â€Å"a much larger chance to be relevant†. The carbon calculus concerns not only electricity but also ethanol, called â€Å"closet carbon†. There are possibilities to reduce greenhouse-emissions producing ethanol from trash through a newly-elaborated thermochemical method, proposed by Range Fuels of Denver. Nowadays we use corn ethanol, made using natural gas and coals, containing carbon, and sugar-cane ethanol, resulting in 10% as much CO2. Another approach, being tested in Arizona, is to fertilize algae with carbon dioxide captured from the atmosphere. Scientists even propose carbon-negative products, such as synthesis gas made from biomass, with resulting carbon dioxide being captured chemically. New approaches are sought for in architecture. Today building sites are evaluated for solar orientation and prevailing winds, the possibility to use the existing mass of hillsides and the ambient temperature of the dirt, etc. Carbon dioxide emissions can be reduced in the process of produce of various goods for mass consum ption. The problem is that the new technologies
