While using wood for energy to heat a home has a romantic association for many people, it is an inconvenient energy source. Most wood heat requires humans to bring in firewood, monitor the fire and add more fuel on a regular basis. This lifestyle commitment does not work for everyone.Know More
Use of wood heat tethers the occupant to the home. Unless someone feeds the fire every few hours, it goes out. Unless a home has an alternative heat source, in areas where temperatures are low, the homeowner faces the danger of frozen plumbing due to a lack of heat in the home. Many wood heat sources are inefficient. Fireplaces are notorious for removing more heat from a home than they supply.
For consumers with access to wooded areas and the ability to gather firewood, using wood energy for heat sometimes saves money. A cord of wood provides about the same amount of energy as burning 130 gallons of fuel oil. However, cutting and hauling firewood is hard work and requires an investment in time. After cutting, wood requires seasoning for several months in a dry location to provide the maximum amount of heat. Seasoning also reduces dangerous creosote buildup in chimneys. When the consumer is unable to gather his own wood, the cost savings are often lost.Learn more about Natural Resources
One of the biggest disadvantages of using oil is that it is a nonrenewable source of energy, which means that once supplies are exhausted, there is no way to produce more. Oil also poses significant risks to the atmosphere and water bodies; oil spills, for instance, cause disastrous effects to local environments by destroying plants and organisms and are often expensive and time consuming to clean up.Full Answer >
Biomass is a type of biological material that is derived from organisms. It is a carbon-based product that also contains a mixture of hydrogen, oxygen, nitrogen and alkali earth metals. Biomass is created by organisms as waste products, and it can be used as an energy source.Full Answer >
Green energy refers to energy derived from renewable sources with a low environmental impact and includes solar, wind, geothermal, biogas and hydroelectric energy. Green energy sources don't create harmful greenhouse gases at the same rate as fossil-fuel energy sources.Full Answer >
The propellers of wind turbines are rotated by the wind and activate a generator, which produces electricity. Wind turbines harness the power of air moving from a high pressure location to a low pressure location. The propellers on a wind turbine are aerodynamically shaped to rotate when wind passes through them.Full Answer >
