...Your cover story provides a distorted, inaccurate picture of biofuels. The overwhelming body of data demonstrates the carbon benefits of biofuels. For every unit of energy it takes to make domestic biodiesel, 3.5 units are gained, giving biodiesel the highest energy balance of any liquid fuel. In 2007 alone, biodiesel's contribution to reducing greenhouse-gas emissions was the equivalent of removing 700,000 passenger vehicles from America's roadways. The U.S. biodiesel industry strongly opposes rain-forest destruction and nonsustainable agricultural practices. Biodiesel increases our renewable-energy supply, adds well-paying, green jobs to the economy and reduces carbons...
...Remember basic high-school science, where an electric current passed through water produces hydrogen and oxygen? Get the electricity from solar power, collect the hydrogen to use as fuel, and carbon doesn't even enter the equation. Honda, Mercedes-Benz, General Motors and BMW have new models that run on hydrogen, but we don't see much enthusiasm from governments. Is it because hydrogen, being so simple to generate, could be too difficult to tax? John Don, Karalee, Queensland...
...most dramatic effects include stronger storms that destroy coastal cities such as New Orleans, rapidly receding glaciers, spring arriving earlier, and invasive species moving into new, warmer areas. According to the Intergovernmental Panel on Climate Change, “The world will have to end its growth of carbon emissions within seven years and become mostly free of carbon-emitting technologies in about four decades to avoid killing as many as a quarter of the planet’s species from global warming.” These tragic effects, however, in a twist of cruel irony, will likely impact most...
...hour of power, a natural gas plant still releases approximately twice the net CO2 of a photovoltaic plant, three times more than hydroelectric plants, and 14 times more than wind farms. If Massachusetts wants to prevent climate change, it should not be choosing fuels that release inordinate amounts of carbon dioxide. Symbolically and realistically, coal goes against the very meaning of green energy. The second argument of coal gasification enthusiasts is that coal plants are a necessary part of the Massachusetts energy landscape, so we ought to simply make them as clean as possible. If we cannot eliminate coal...
...should be a vanguard in promoting sustainability. However, in comparison to the City of Boston’s aggressive environmental campaign, Harvard’s efforts have looked half-hearted. According to the Harvard Green Campus Initiative, Harvard’s greenhouse gas emissions, measured in metric tons of carbon dioxide equivalent (MTCDE), have continued to climb over the past 16 years despite the University’s recent attention to sustainability. Notably, emissions from the Cambridge campus are significantly more than Longwood’s; the Faculty of Arts and Sciences accounts for 37 percent of emissions, more than...
