Why Dems are so bent on passing wind amid corona crisis

Why Dems are so bent on passing wind amid corona crisis By Robert Bryce March 27, 2020 | 8:34pm Shutterstock Stop me if you’ve heard this before: Renewable energy is getting so cheap that it doesn’t need subsidies anymore. Yes, well. Renewables live or die by subsidies, in fact. That was proved yet again this week, when Democrats tried (unsuccessfully) to stuff a panoply of Green New Deal measures into the corona-crisis relief bill — including extensions of the tax credits that have been driving the growth of solar and wind energy. That Congressional Democrats would push so hard for solar and wind subsidies at such a critical time for the US economy is particularly galling for two reasons. First, the wind industry already stands to collect some $33.75 billion in subsidies between now and 2029. Second, wind-energy development in some of the most-heavily Democratic states in the country — Hawaii, California, New Yo

Why Clouds Are the Key to New Troubling Projections on Warming

Why Clouds Are the Key to New Troubling Projections on Warming By Fred Pearce • February 5, 2020 Recent climate models project that a doubling of atmospheric CO2 above pre-industrial levels could cause temperatures to soar far above previous estimates. A warming earth, researchers now say, will lead to a loss of clouds, allowing more solar energy to strike the planet. It is the most worrying development in the science of climate change for a long time. An apparently settled conclusion about how sensitive the climate is to adding more greenhouse gases has been thrown into doubt by a series of new studies from the world’s top climate modeling groups. The studies have changed how the models treat clouds, following new field research. They suggest that the ability of clouds to keep us cool could be drastically reduced as the world warms — pushing global heating into overdrive. Clouds have long been the big

A reality check on electric cars: Arithmetic required

A reality check on electric cars: Arithmetic required By Bill Lynch , Dr. Jay Lehr | March 6th, 2020 | Energy | 23 Comments During the Obama Administration a regulation was passed requiring all automobile manufacturers to achieve an average efficiency for all their vehicles of 54 miles per gallon by the year 2025. President Trump recently canceled the ordinance recognizing such a requirement could never be reached without sacrificing the safety of the drivers which we will attempt to explain. A simple tutorial requiring a little arithmetic follows, and the fallacy of the benefits of electric cars will slowly dissolve. The energy in gasoline is not appreciated. An automobile that gets 40 miles per gallon uses only six tablespoons of gasoline traveling each mile. As good as that sounds, cars cannot be perfectly efficient. There must be friction resistance just to get them going and there is no avoidance of aerodynamic
