Comparison of sources of power
While selecting a method of generating electricity, following factors should be taken into consideration
1. Initial cost
To produce a given rating of a unit (in the minds of planners), investment must be known. Naturally lower the initial cost, better it is
2. Running cost
To produce a given amount of electrical energy, the cost of conversion process (including proportional cost of maintenance/repairs of the system) has to be known.
Whether a particular resource is available, whether a unit size of required rating is available from a single unit or from a large number of units
4. Perpetuity, efficiency ,reliability, cleanness and simplicity
It is naturally desirable that the source must have perpetuity (=be of endless duration), high conversion efficiency and reliability (in terms of availability in appropriate quantity. The energy conversion must be through a cleaner process (especially from the view point of toxicity, pollution or any other hazardous side effects). Further, a simpler overall system is always preferred with regards to maintenance/repairs problems and is supposed to be more reliable.
Sources for generation of electricity Electrical energy is produced from many different energy sources. Some of these energy sources are renewable and others are non-renewable. Non-renewable come out of the ground as liquids, gases and solids. These resources are crude oil (petroleum), natural gas, propane and coal. Another non-renewable source is nuclear fission power. These sources cannot be replenished in a short period of time. Renewable resources are not subject to depletion in a human timescale. These sources include the sun's ray, waves, rivers, tides, wind, biomass and the heat from radioactive decay in the Earth's core.
Considering above factors, Darrvishi holding has selected two types of sources for generation of electricity. The first one as a renewable source of energy and the second one as a non-renewable source.
