No reliable estimates are available for the total amount, but it is substantial in the US and around the world.
It should be noted that electrical generation is inherently "wasteful," because maintaining voltage across an entire electrical grid creates waste heat in the circuits and Transformers. However, reducing unnecessary electrical consumption benefits consumers by lowering their bills, and also forestalls the need for additional capacity to be constructed to meet peak needs.
Cost per unit of electricity depends the type of generation used. ie:- thermal hydel, nuclear etc. hydel electricity is cheaper and now a days it cost less than Rs.10 per unit in India. whereas thermal electricity cost less than Rs. 20 per unit

13,600 miles per second :-) True dat
http://www.booneelectric.coop/coop/tips2.htm According to this webpage the average garage door opener is 800 watts and uses 6¢/hr worth of electricity (based on a 8 cents per kilowatt hour electric rate).
It depends on the system and the operating speed of course but as anexample of a typical monorail used for public transportation the Wuppertaler Schwebebahn uses 2.98kWh/km or 1.85kWh per train mile.This translates to approx. 2.25kWh per passenger km (1.4kWh/passenger mile)
at present 19500MW is produced in Pakistan
155 per person
About 39 million gallons are wasted a year in traffic for the average person. Think about how many gallons are wasted a year in the whole world.
6000 kilo watts
24hours * 60mins * 365.25 Days * 30drops = 15778800 drops per year I would suggest getting your tap fixed as your bill is gonna be very high due to the drip.
The amount of electricity that is used on a farm in a year will vary depending on the size of the farm. It averages about 35,000 kilowatts per year.
The amount of water wasted in a year can vary greatly depending on various factors such as location, population, and water usage habits. On average, a single person in the US can waste around 30 gallons of water per day, which adds up to about 10,950 gallons per year. Scaling that up to a family of four, the wasted water can reach over 43,000 gallons per year.
Electricity in the US cost about ten cents per kilowatt-hour. The average family uses about 10,000 kilowatt-hours per year. So that's about $1,000 per year. This is one of the reasons why alternative energy is so difficult to implement--your electricity is really a bargain.
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.
about 2 sheets a day. But if that goes on for a week, 14 sheets of paper are already wasted!
A large Bunn coffee machine uses about $23 worth of electricity per year. A regular 12- cup coffer maker only uses about $12 worth of electricity per year.
25 units per day (winter), 10 units per day (summer).
