Sadly a great deal of electricity is wasted.
A lot

Globally, it is estimated that around 10% of electricity is wasted due to inefficiencies in generation, transmission, and consumption. This translates to approximately 2,000 terawatt-hours (TWh) annually, enough to power hundreds of millions of homes. In the United States alone, about 60 billion kilowatt-hours are wasted each year, primarily through outdated infrastructure and energy-inefficient appliances. Reducing this waste is crucial for improving energy sustainability and lowering greenhouse gas emissions.
1.7% of Pakistan electricity is produced by nuclear power stations
On average, power plants in the United States waste about 60% of the energy they generate as excess heat discharged to the environment. This wasted energy results from inefficiencies in converting heat into electricity and in transmitting electricity over long distances. Efforts to improve efficiency and reduce waste at power stations are ongoing through advancements in technology and infrastructure.

Energy input minus useful energy output. So if you were using a lamp you could work out how much energy was going in and how much was actually coming out in light. Then whatever's leftover is being wasted.
It nearly 10 liters of water is wasted
Vast amounts of solar energy land on the earth every day, and only a tiny amount is captured for generating electricity. It is hardly being wasted, though, as much of it is used to warm the earth, to grow crops, to power photosynthesis in plants etc.
Generally, schools usually use about 10 kWh of electricity per square foot annually. A medium sized school spends about $1 million on electricity a year.
