A recently proposed wave energy power system off the south western coast of Africa estimated their construction cost to be $2.9-million per MW.
The most cost effective wave energy generation plants are operating around 7.5 cents per kWh, as opposed to coal fired power stations at 2.6 cents/kWh.

What does the power rating of an electrical appliance mean?
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
How much energy does a 5 watt light bulb produce?
A 5 watt light bulb produces 5 joules of energy per second.
How much energy does a natural gas power station produce per day?
The energy produced is related to the size of the power plant, not the amount of gas it uses. The question you really want answered is "How much gas does it take to produce a kilowatt of electricity?"
How much energy is stored in a computer?
The energy stored in a computer is typically in the form of electrical energy, stored in the battery or power supply unit. The amount of energy stored depends on the capacity of the battery or power supply, which can vary based on the device and its specifications.
What energy changes take place when a light switch is turned on?
mechanical to electrical to light energy
How does fluorescent light bulbs help conserve energy?
It's because it need only 20% of the electrical power to produce as much light, therefore less energy is wasted.
How much electrical energy is produced by a light bulb with the power ratings of 60w?
A lamp doesn't produce electrical energy; it utilises it. The power-rating of the lamp will tell you the rate at which that lamp uses expends energy at its rated voltage. For example, a 60-W lamp will expend energy at 60 joules per second.
What will the electricity of a wind turbine cost?
This is a question of how much electrical energy you want to produce, against the cost of the equipment to produce it.
What does the power rating of an electrical appliance mean?
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
How much energy does a 5 watt light bulb produce?
A 5 watt light bulb produces 5 joules of energy per second.
How much energy can nuclear supply?
The latest PWR designs can produce 1600MW electrical from one reactor.
How much heat energy is produced from 3000 joules of electrical energy?
The amount of heat energy produced from electrical energy depends on the efficiency of the system. If we assume 100% efficiency, then all 3000 joules of electrical energy would be converted into heat energy. Thus, 3000 joules of electrical energy would produce 3000 joules of heat energy.
What is the relationship between appliances power rating and the amount of heat it produce?
power rating is the rate of moving energy their relationship in the amount of heat it produce it divided by time to move that much energy
Does nuclear fuel produce sixty eight percent of the electrical energy in US?
No, much less, about 20 percent at present
How much of the total energy produced in the US is electrical energy?
73 % is electrical energy
How do you work out how much energy is transferred by an electrical device?
You can calculate the energy transferred by an electrical device using the formula: energy (in joules) = power (in watts) × time (in seconds). Simply multiply the power consumption of the device in watts by the time period it is operating in seconds to determine the energy transferred.
How much electrical energy was produced by nuclear power plants?
2,598,000,000,000 kWh a year, that was estimated in 2008.
