People interested in using green energy for their homes have many options. Benefits of using renewable energy systems include long term savings on energy and helping the environment. Initial costs of installing these systems can be expensive at first glance. Incentives with state and federal agencies can help offset these costs.

Wind Power

One form of green energy is wind power. Wind turbine towers for residential use can be connected to electrical system of a household. For residential use, wind speeds in the area need to be consistently at least 10 miles per hour with 12 miles an hour or more being desirable. Benefits to these systems are that wind source is free and no waste is produced. The drawback is that if wind is not constant, the system is not as reliable. Rotor size of the turbine is the best gauge of output. Costs of systems can vary based on size of windmill tower and distance from the electrical connection.

Solar Power

Another common source of green energy is solar power. Solar photovoltaic systems use energy from the sun that is collected in panels of solar cells. Energy collected in the cells is then converted into electricity. Some downsides to these systems are that sun energy is not available at night and the systems can be expensive. However the cost is coming down as newer more efficient systems emerge. Panels do need to be set in certain areas for best exposure. Federal and state incentives are available to offset installation costs. To qualify for many of these incentives, energy systems need to be put in by certified installers.

Hydroelectric Power

For residents who have a river or stream on their property, hydroelectric systems are an option for green energy. These kinds of systems provide low costs to operate and can be a constant source of energy with enough water flow but can be expensive to build. Flow of water is equally rated so a small high stream can be as productive as a large stream. Systems can be extensive with turbines and pipelines in the system. Federal grants are available but few states have incentives at this time. State and local permits may also be required for these systems.

Heat Pumps

Ground source heat pumps are another source of green energy for home owners. Liquid based heat pumps built into the ground beneath a basement moves heat from the house to the ground in the summer and the ground to the house in winter. These systems need little maintenance. System installation is less with new construction but can increase for existing structures. Systems are a good source of green energy as they are very productive, constant, and efficient. Federal incentives are available.

The key to any good green energy is the return on investment. One positive trend of companies that provide green energy systems is that they have full service programs for their customers from design, funding, and installation. Customers should review cost savings with their service provider.
