The power rating 100W means the bulb consumes electrical energy of 100 Joule per second. Joule is the SI unit of energy. 1 Watt-hour is equal to 3600 Joules. The filament of an electric bulb is made up of tungsten. … Continue reading →

Energy drives economies and sustains societies. Energy production and use is also the single biggest contributor to global warming. The energy sector accounts for about two-thirds of global greenhouse gas emissions attributed to human activity. Why is energy consumption important? … Continue reading →

The electrical efficiency of the lithium-ion battery is defined as the product of voltage efficiency and coulombic efficiency, ηel = ηU ηC. The low IR and the lack of significant side reactions result in coulombic efficiencies (capacity discharged over capacity … Continue reading →

Thermal energy storage. Electricity can be used to produce thermal energy, which can be stored until it is needed. For example, electricity can be used to produce chilled water or ice during times of low demand and later used for … Continue reading →

Such storage may be to reduce demand on the grid, as back-up, or for price arbitrage. Pumped storage projects and equipment have a long lifetime – nominally 50 years but potentially more, compared with batteries – 8 to 15 years.Such … Continue reading →
