The Wind Vision Report  takes America’s current installed wind power capacity across all facets of wind energy (land-based, offshore, and distributed) as its baseline—a capacity that has tripled since the 2008 release of the Energy Department’s 20% Wind Energy by 2030 report—and assesses the potential economic, environmental, and social benefits of a scenario where U.S. wind power supplies 10% of the nation’s electrical demand in 2020, 20% in 2030, and 35% in 2050. The Wind Vision Report builds upon the continued the success of the wind industry to date and quantifies a robust wind energy future

Geothermal heat pumps are able to heat, cool, and, if so equipped, supply homes and buildings with hot water. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger buried in shallow ground.

In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system.

In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to provide a free source of hot water.

There are four types of geothermal heat pump systems.

DISTRIBUTED ENERGY SYSTEM

Distributed energy consists of a range of smaller-scale and modular devices designed to provide electricity, and sometimes also thermal energy, in locations close to consumers. They include fossil and renewable energy technologies (e.g., photovoltaic arrays, wind turbines, microturbines, reciprocating engines, fuel cells, combustion turbines, and steam turbines); energy storage devices (e.g., batteries and flywheels); and combined heat and power systems.

Distributed energy offers solutions to many of the nation's most pressing energy and electric power problems, including blackouts and brownouts, energy security concerns, power quality issues, tighter emissions standards, transmission bottlenecks, and the desire for greater control over energy costs.
