1. Waste at home translates into higher utility bills.(loss of money)
2. Causes extra pollution because of pollution created by power plants generating wasted electricity
3. If enough homes waste causes more energy to be needed which can result in brown out slash blackout or other loss of service in the short term and in the long term results in a need for new power plants which are very expensive for the community and also increases pollution and more often than not drops property values in the area around where it is constructed.
4. Depending on the type of power plant built it could result in health issues for nearby wildlife and human population.
