A review of renewable energy based power supply options for …
Merei et al. (Merei et al., 2013) have studied the economics of employing three distinct battery technologies for a PV–wind- and DG-based hybrid system. Vanadium-redox-flow battery technology has been found to be the cheapest ($0.73/kWh) against the lead-acid ($0.77/kWh) and Li-ion batteries technology ($0.81/kWh).

Technology Primer – Power Supply Wattage and Efficiency
Efficiency in this sense refers to how much of the power drawn from the wall is turned into usable energy inside the computer. For example, if a power supply is providing 720 watts to the system and operates at 80% efficiency then it will be drawing 900W from the wall (900W x 80% = 720W). The same situation with a 90% efficient …

How to Choose a PC Power Supply
If you use a power supply with an 85% efficiency rating, your PC will pull about 353 watts of input power from your power company. A power supply that''s only 70% efficient, on the other hand, will pull 428 watts of power from the wall. Choosing the more efficient power supply will save some cash on your monthly power bill.

For now. Power = rate of doing work Watts or kiloWatts (1000 Watts = 1 kW.) Energy or work done is measured in Joules. 1000 Joules = 1 kiloJoule = 1 kJ. In one hour at one Watt we use 1 W x 3600 s = 3600 Joule = 3.6 kJ. Battery energy = Volts_average x Amp hours capacity = Watt hour capacity.
