In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity.[1][2][3] Power is a scalar quantity.

Specifying power in particular systems may require attention to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction force on the wheels, and the velocity of the vehicle. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element.[4][5]

The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts. Other units of power include ergs per second (erg/s), foot-pounds per minute, dBm, a logarithmic measure relative to a reference of 1 milliwatt, calories per hour, BTU per hour (BTU/h), and tons of refrigeration.

As a simple example, burning one kilogram of coal releases more energy than detonating a kilogram of TNT,[6] but because the TNT reaction releases energy more quickly, it delivers more power than the coal.If W is the amount of work performed during a period of time of duration t, the average power Pavg over that period is given by the formula P a v g =  W  t . {\displaystyle P_{\mathrm {avg} }={\frac {\Delta W}{\Delta t}}.} It is the average amount of work done or energy converted per unit of time. Average power is often called "power" when the context makes it clear.

Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity.

In fluid power systems such as hydraulic actuators, power is given by P ( t ) = p Q , {\displaystyle P(t)=pQ,} where p is pressure in pascals or N/m2, and Q is volumetric flow rate in m3/s in SI units.

In the case of a periodic signal s ( t ) {\displaystyle s(t)} of period T {\displaystyle T} , like a train of identical pulses, the instantaneous power p ( t ) = | s ( t ) | 2 {\textstyle p(t)=|s(t)|^{2}} is also a periodic function of period T {\displaystyle T} . The peak power is simply defined by: P 0 = max [ p ( t ) ] . {\displaystyle P_{0}=\max[p(t)].}

EPA has issued final carbon pollution standards for power plants that set carbon dioxide (CO2) limits for new gas-fired combustion turbines and CO2 emission guidelines for existing coal, oil and gas-fired steam generating units, securing important climate benefits and protecting public health.

On March 26, 2024, EPA opened a non-regulatory docket and issued framing questions to gather input about ways we can design a stronger, more durable approach to greenhouse gas regulation of the entire fleet of existing gas combustion turbines in the power sector under Clean Air Act 111(d).

These rules will significantly reduce greenhouse gas (GHG) emissions from existing coal-fired power plants and from new natural gas turbines, ensuring that all long-term coal-fired plants and base load new gas-fired plants control 90% of their carbon pollution. Existing coal-fired power plants are the largest source of GHGs from the power sector. New natural gas-fired combustion turbines are some of the largest new sources of GHG being built today and these final standards will ensure that they are constructed to minimize their GHG emissions.

e-POWER is Nissan's unique electric-drive powertrain that integrates a gasoline engine and motor.

 Since the engine only generates electricity and the system is 100% driven by a high-output motor, it is possible to enjoy the driving experience of an EV.

 e-POWER utilizes motor control technology cultivated in past EV development activities, powertrain integration technology, and energy management technology. By changing the combination of electric-drive motors and power-generation engines, it delivers quiet driving with excellent response over a wide range of vehicles from compact cars to minivans and SUVs.

Since e-POWER is 100% motor-driven, it provides a responsive and powerful driving experience, by taking advantage of the characteristic that the motor can generate maximum torque from when it starts.

 The system can freely control engine start timing because the engine is not directly connected to the wheels. It provides very quiet driving with reduced engine operation time by driving the vehicle with just the motor from start to low/mid-range speed and starting the engine and generating electricity in fast speed areas with elevated road noise. It also achieves low fuel consumption because it generates electricity at efficient engine RPM.

The e-POWER system is comprised of a high-voltage battery and the powertrain, which is integrated with a high-power motor, inverter, gasoline engine, and a generator. In conventional hybrid systems, the wheels are driven by an electric motor and a gasoline engine. However, in the e-POWER system, the wheels are driven by a high-output electric motor like an EV.

 Since the engine connected to the generator only charges the battery and does not directly drive the wheels, it is possible to freely set the start timing and efficient RPM. Generated electricity charges the high-voltage battery and directly drives the motor.

The second-generation e-POWER system delivers an attractive experience over a wide range of vehicles from compact cars to minivans and SUVs with a compact and high-output integrated inverter and motor and optimal engine combinations.

 The e-POWER system in compact cars is in a compact engine room with a 1.2L engine. Despite the low-displacement engine, this system realizes motor-driven performance that generates high torque from when it starts and beyond-class powerful, smooth acceleration.

 For minivans, Nissan developed a dedicated e-POWER engine that realizes EV-like driving even with a heavy vehicle body. By using a dedicated e-POWER engine, it is possible to have an optimal design that factors in integration and realizes high unit rigidity. Nissan curtails engine vibration through a synergy effect with a primary balancer shaft and flexible flywheel. Hence, it delivers excellent quietness even at times with high engine RPM for scenarios situations requiring large amounts of power generation, such as passing another vehicle.

 For SUVs, Nissan simultaneously achieves overwhelming power and excellent quietness at a high level by combining the e-POWER system with its proprietary variable compression ratio engine (VC turbo engine). Combined use of the engine and turbocharger enables the vehicle to deliver high torque on par with a large displacement engine, despite the 1.5L, small-displacement engine that it has, by lowering the compression ratio and raising boost pressure, such as when driving at full throttle. Delivery of a high power-generation capacity at low RPM with this design provides quiet and comfortable driving in all situations.
