The largest grid operator in the U.S., PJM Interconnection, has warned of apower shortfallas coal plants are retired faster than new capacity is brought online. PJM operates the grid in all or parts of 13 states, in the Mid-Atlantic, Midwest and South. The situation could become more acut...
Fossil fuels make use of a considerable amount of water to get converted to electricity. Not only this, coal and gas-fired power plants also use huge quantities of water to get cooled. During hydraulic fracking, which is a process of extracting natural gas as well as oil, a large amount ...
But China's use of coal to meet its surging demand for electricity has caused a secondary problem:dirty air. "With the huge growth in coal use, along with a dramatic increase in private vehicle ownership, has come a dire need for more clean electricity generation," Kotek told CNBC. ...
Nuclear waste remains dangerous for 250,000 years, which greatly increases the security problem attached to its potential for use in nuclear weapons. The nuclear industry argues that, as an electricity generator that does not produce greenhouse gases, nuclear power should have a role in combating ...
Castro said that a study in Orlando found that the city’s buildings are responsible for 80% of its greenhouse gas footprint, primarily as the electricity it consumes is from fossil fuels like coal and some natural gas. The city committed to use entirely zero emission electricity by 2050, ...
The Trump administration also said it is ready to cancel what it called, "harmful and unnecessary policies." Among them is the Obama administration’s plan to reduce pollutants from coal-powered electricity plants. The climate plan was designed to cut gases that cause global warming. Another is...
Using renewable electricity at large scale will reduce energy intensity, replacing bulk coal, liquefied petroleum gas, etc. Battery technology is mature enough to make electricity cheaply stored for a long period. The transformation of the energy consumption structure of electric energy is also ...
When measuring the electric power generation fueled by natural gas, the difference in cost is the spark spread. When analyzing coal, the difference is called the dark spread. What Do Spreads Indicate for Electricity Consumers? Changes in spark spreads in an electricity power market indicate the op...
Although cap and trade systems reduce emissions and can lead to faster cuts in pollution, they also tend to increase the price of oil, coal, andnatural gasin an effort to force companies to switch to alternative forms of energy. These initiatives are expensive and impact negatively the economy...
