What Are Nebulizers and Inhalers? Nebulizers and inhalers are tools that help kids take their asthma medicines. Most asthma medicines start out in liquid form. In order to work, they need to be breathed into the lungs. Nebulizers and inhalers turn liquid medicine into a mist so that kids can breathe it in. Some inhalers release the medicine in a fine powder form that also can be breathed in. These tools are effective when used properly.
Also, as electricity becomes a larger part of our transportation system it can directly displace imported oil. Direct use of geothermal heat for certain commercial, industrial and agricultural uses, provides an alternative to other sources of thermal energy including electricity, natural gas, propane, or oil.
Why is geothermal energy renewable source of energy? Geothermal energy (earth's thermal energy in form of heat generated and stored in Earthâs core) is renewable source of energy because earthâs heat is practically inexhaustible source of energy that is being replenished by radioactive decay of minerals at a rate of 30 TW.
