In our latest Short-Term Energy Outlook (STEO), we forecast that electricity generation from U.S. hydropower plants in 2024 will be 13% less than the 10-year average, the least amount of electricity generated from hydropower since 2001. Extreme and exceptional drought conditions have been affecting different parts of the United States, especially the Pacific Northwest, which is home to most U.S. hydropower capacity.

A recent study has compared the impact of future power generated from large, central stations with power generated from smaller distributed generators (DG) in California on air quality. It concluded that although DG produces more emissions, its impact on air quality is likely to be smaller than central power stations due to complex interactions between air chemistry and transport.

A power generation and control system is easily installed in a consumer household, a business, or an end-user establishment for generating power and preventing power from flowing to a power grid from a consumer circuit during a power outage. A communications transceiver is adapted to transmit a permission signal for allowing power generation only after the control system has been installed. The control system can be adapted to replace an existing circuit breaker in a household circuit breaker box and prevents power from traveling from consumer power generators to the grid during a power outage. In the same manner that end-users can add appliances to existing circuits, end-users can easily add additional power generation devices without hiring a professional electrician and without worrying about causing harm to utility workman during power outages.

An electric power generation system (EPGS) employs both a wild-source generator and a variable and/or constant frequency generator. The wild-source generator is coupled to receive mechanical power from a low-pressure spool on an aircraft engine and to generate in response a wild-source output for consumption by voltage and frequency-tolerant loads. The variable and/or constant frequency generator is coupled to receive mechanical power from a high-pressure spool on the aircraft engine and to generate in response a variable and/or constant frequency output for consumption by voltage and frequency-intolerant loads.

[Problem] To provide a photovoltaic device capable of generating power whether day or night, without affecting the appearance of a structure or reducing lighting or other functions, and able to inhibit rises in room temperature by converting thermal radiation into electrical energy. [Means to Solve Problems] Provide a photoelectric conversion element 3 with a photovoltaic device 1 on structural members 2a-2d facing the outside of a house or other structure. Power generated by the photoelectric conversion element 3 is extracted via a power extraction unit 4. The power conversion element 3 includes a semiconductor layer 11, conductive layer 20, a metal nanostructure 30 having multiple periodic structures 33, a first electrode 41 and a second electrode 42. The first and second electrodes 41, 42 are separated in the direction of the surface of the photoelectric conversion element 1 with the terminals 71, 81 of the power extraction unit 4 respectively connected.

A turbofan engine (10) employs a flow control device (41) that changes an effective exit nozzle area (40) associated with a bypass flow path (B) of the turbofan engine. A spool (14) couples a fan (20) to a generator (52). The turbofan emergency power system includes a controller (50) that communicates with the flow control device (41). Upon sensing an emergency condition, the controller manipulates the flow control device to reduce the effective nozzle exit area (40) of the bypass flow path, which chokes the flow through the bypass flow path thereby increasing the rotational speed of the fan. In this manner, the generator is driven at a higher rotational speed than if the flow through the bypass flow path was not choked, which enables a smaller generator to be utilized.

An electrical generator is driven by gravitational force provided by a plurality of pairs of water tanks. Each pair of water tanks is suspended by an elongated chain supported by a series of pulleys. The water tanks in each pair of water tanks move between an upper position and a lower position alternately by filling selected ones of the water tanks with water and draining from the other selected ones of the water tanks. The vertical movement of the water tanks alternately filled with water is translated by ratchet wheels and bevel gear wheels to rotate the electrical generator in the same direction for generating the electrical power.

A rigid arm pendulum is combined with a helical device attached to the pendulum horizontal axle to provide a double reciprocating action. While the pendulum reciprocates in rotary fashion about the axle, describing successive arcs of less than 360 degrees, the axle simultaneously produces a reciprocating action about its longitudinal centerline. A pumping action is thereby developed in line with the longitudinal centerline of the axle. This pumping (linear reciprocating) action can be utilized for a variety of requirements, including a hydraulic pump and a system to drive an electric generator.
