Key Terms

megawatts, renewables, energy storage

3 terms

megawatts technical

"and collectively own 55,100 megawatts of energy capacity."

A megawatt is a measure of electrical power equal to one million watts, describing how much electricity a plant or device can generate or use at a single moment. Investors use megawatts to compare the size and earning potential of energy projects—larger capacity usually means more electricity to sell—much like comparing the horsepower of engines to judge how much work they can do. Knowing megawatts helps assess scale, revenue potential, and grid impact of energy assets.

renewables technical

"including natural gas, nuclear, renewables and energy storage."

Renewables are energy sources that are naturally replenished over short time spans—like sunlight, wind, flowing water, and plant-based fuels—used to generate electricity, heat, or fuel. For investors, renewables matter because they represent a shifting energy mix with long-term demand potential, often requiring big upfront investment but offering predictable operating costs and exposure to government policies and incentives; think of them like a rechargeable power supply replacing one-time fuels.

energy storage technical

"including natural gas, nuclear, renewables and energy storage."

Energy storage involves capturing and holding excess energy produced during periods of low demand for later use when demand is higher. Think of it like a rechargeable battery that saves power for when it’s needed most. For investors, energy storage is important because it helps balance supply and demand, making energy systems more reliable and efficient, which can influence the value of energy-related assets and technologies.
