A New Ki nd of Technology Since electricity is four times as expensive as natural gasfew sane Americans would heat their homes with electricity, but it happens. I have lived in homes heated with electric heaters several times, mainly because of all the hydroelectric projects in Washington State.
When I lived in New Jersey, my apartment had electric heat. Gas furnaces cost thousands of dollars, while electric heaters cost a small fraction of that. Electric lines run in places where gas lines are too difficult to install. Gas has its dangers, such as explosions and asphyxiation reduced because artificial scent is added to natural gas, so leaks are easily detected in the home.
Electricity has its hazards, such as electrocution and radiation from high voltage lines. Millions of homes have heat pumps. If a heat pump can average a COP of two, then it would be twice as efficient as using that electricity to run space heaters. Wh y are any heat pumps sold in the United States, if electricity is four times as expensive as natural gas?
If a heat pump averages a COP of two, then electricity is still twice as expensive as burning natural gas for heat. There are regional variations in electric and gas prices, which can make the relationship closer, however.
In addition, there are variables in the economics of producing electricity. For instance, the electricity production infrastructure is geared toward meeting peak demand. At night and in the winter, demand can slacken dramatically. There are technical and practical issues with turning on and off electric company steam turbines.
Electric company turbines run all the time, but idle during off-peak hours. Electric companies have long encouraged businesses to use electricity at off peak hours, and do so with preferential pricing. For instance, in the early 20th century, the Niagara Mohawk electric company charged more than 17 cents per kilowatt-hour kWh at peak times, and less than four cents per kWh on off peak.
Also, if a home or business uses electricity for heating, electric companies can give preferential pricing. What if heat pumps could get COPs of eight? Then heat pumps could operate at half the operating cost of natural gas furnaces. A diagram of a standard air-to-air heat pump is presented below.The table below presents an abbreviated geologic time scale, with times and events germane to this essay.
Please refer to a complete geologic time scale when this one seems inadequate. This started with a tweet.
I’m embarrassed how often that happens. Frustrated by a sense of global mispriorities, I blurted out some snarky and mildly regrettable tweets on the lack of attention to climate change in the tech industry (Twitter being a sublime medium for the snarky and regrettable).
Climate change is the problem of our time, it’s everyone’s problem, and most of our problem. Of course these turbines and solar panels are built using fossil fuels so they are just another ‘pie in the sky renewable resource.” The building of these turbines has nothing to do with renewable energy!
To distinguish between renewable and nonrenewable sources of energy; to investigate a variety of renewable energy resources and compare the benefits and drawbacks of each. Students will use Internet resources to investigate and compare alternative sources of energy. It is presumed that students have.
