The biochar can also act as a habitat for many soilbased microorganisms. Microbial life has been shown to be a real necessity in gardening. Beneficial microbes help plants to take up nutrients more readily. They also help defend against plant diseases. Providing housing for the microbes is a good idea, and it improves overall soil health too!

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...
