To compare the usable heat for various types of fuels, you must know the available heat value of the fuel and the operating efficiency of the heating system. The available heat value of fuel is measured in British thermal units (Btu), and each type of fuel has a specific Btu content per unit of fuel. By definition, one Btu is the heat required to raise the temperature of o ...
“The problem is not oil and gas. It’s emissions,” Woods told the Asia Pacific Forum on November 15. “The solutions to climate change have been too focused on reducing supply,” he...
mindi woods via oil heat-treatment. The wood specimens were heat-treated at 180°C, 200°C, 220°C, and 240°C in palm oil for 1 h, with a heating rate of 2°C/min. The effect of...
Those reductions are planned because burning such carbon-dense fossil fuels in power plants, cars and factories is far and away the biggest driver in the rise in global temperatures and extreme weather. But the reporting from the Guardian, which draws together both projections from the federal Energy Information Agency and recent U.N. reports, suggests that the U.S. has set itself an impossible chronology: a long plateau of high fossil fuel production that continues to mid-century — before som...
Unlike in the 1970s when we were by necessity looking for alternative heating sources to address oil scarcity, the discussion today increasingly is on living more gently on the earth. Evidence of climate change and burgeoning concerns about the ...
