Alternative fuels have the potential to provide significant economic and environmental benefits to airports and their communities. These fuels can lead to improvements in local air quality emissions and reductions in life-cycle greenhouse gases. In addition, alternative fuels offer the possibility to diversify away from imported conventional petroleum-derived fuels and enhance energy security. Furthermore, alternative fuel distribution programs offer airports additional business opportunities to generate revenue through the operation of such facilities or leasing of land to third-party operators. Airports are natural nodes for multi-modal demand and are ideally situated to become distribution centers for a variety of alternative fuels for aircraft and surface transportation. Producers and marketers of alternative fuels can take advantage of this concentrated demand to strengthen their business case as they can cater to a wide spectrum of potential clients, including airlines, airports, and third-party operators such as rental car facilities, courtesy shuttles, taxis, buses, freight trucks, and other fleets that may operate nearby. This is especially the case for facilities that produce alternative jet fuel because, in addition to jet fuel, they also produce co-products such as green diesel, which can be used by some passenger and most cargo vehicles.

A novel intelligent online demand management system is discussed in this chapter for peak load management in low voltage residential distribution networks based on the smart grid concept. The discussed system also regulates the network voltage, balances the power in three phases and coordinates the energy storage within the network. This method uses low cost controllers, with two-way communication interfaces, installed in costumers' premises and at distribution transformers to manage the peak load while maximizing customer satisfaction. A multi-objective decision making process is proposed to select the load(s) to be delayed or controlled. The efficacy of the proposed control system is verified by a MATLAB-based simulation which includes detailed modeling of residential loads and the network.

In the event of a power outage, a UPS system is used to power infrastructure until a generator takes control of the system. UPS systems are generally used for short periods of time, from a few seconds to a few minutes. They are triggered automatically when power supply is interrupted between the mains and the equipment. UPS systems are widely used in the telecommunications,IT, oil and gas, chemical, and food processing industries.

A power cable is an insulated strand of wires that is used to transmit electricity at variable voltage levels. Power cables are mainly used in overhead lines, buildings, and underground wiring applications. They are available in various sizes and shapes according to the requirements of the telecommunications, electrical equipment, construction, and motor vehicle industries. Power cables can be classified into four broad categories depending on their operating voltage applications: low voltage, medium voltage, high-voltage, and extra-high-voltage.

Permanent magnets are made of ferromagnetic materials that create their own magnetic field. They can be broadly classified into rare earth magnets, ferrites, SmCo-based permanent magnets, and other magnets. Rare earth magnets are powerful permanent magnets made from rare earth elements. Unlike electromagnets, permanent magnets do not require continuous electric energy to maintain their electric field. They can retain their magnetic properties even when removed from a magnetic field. This makes permanent magnet motors preferable over electromagnetic motors.

Motors are widely used across industry verticals to convert electrical energy into mechanical energy. Motors are used for applications such as industrial pumps, machine tools, power tools, and household appliances. They can be classified in terms of their power consumption and their mode of operation. For this report, Technavio has considered low-voltage motors that require 690 volts or less to operate. These motors are used predominantly in the HVAC, food and beverage, oil and gas, and mining industries.

Energy-harvesting devices convert ambient energy from the natural environment — such as solar, wind, tidal, and chemical energy — into electrical energy. During the energy-harvesting process, a transducer converts the ambient energy into a small amount of electrical energy that can be used for low-power applications. Energy-harvesting devices allow electronic products to work as contactless charging devices, which make the products highly efficient and reliable for end-users. Energy harvesters discussed in this report include wireless sensor nodes, wristwatches, and solar-plated mobile phones.

Distribution voltage regulators are incorporated into a T&D network by electric utility companies. Voltage levels of the power supplied by these companies undergo numerous fluctuation levels depending on the following factors: Location of the consumer along a distribution line Seasonal and local variations in load factor Distance from voltage regulator equipment Distance from customers that consume large amounts of electric power.

Hydropower is electricity that is derived from the kinetic energy of flowing water. It is an efficient source of renewable energy. In 2014, the global hydropower electricity generation was 3,982 TW. The total installed hydropower capacity is estimated to increase from 1,056 GW in 2014 to 1,446 GW by 2019.
