Wind power: Wind power has been a major contender as the energy source of future. Some of the economic factors hampering the growth of the wind energy are the high estate rentals for wind farms and the high capital costs of turbines and connecting to the grid. However the operational costs of the turbines are very less.
Geothermal: Geothermal energy is another renewable source that can be used. The source is extremely successful in the volcanic regions of the world. The use of this energy to regulate the temperature of homes can be a viable option for replacing ACs and heaters. However, the construction of power grids based on this source is a costly affair.
Biofuels: With a small modification of a car engine, vehicles can be driven by biofuels such as ethanol, biodiesel, or used or unused vegetable oil. These biofuels are cheaper than petrol, have similar performance and emit less toxic gases. However the efficiency of the process in terms of gasoline as input and ethanol as output is still less and needs significant improvement.
Tidal Power: With many of the rivers drying up, the future of hydro power is going to be coming from tidal waves. The major issue facing this energy source is the high maintenance cost of the propellant turbines in the marine environment. However the return in terms of power generated is maximum for the minimum area covered in this case.
Wind energy provides us with a cheap low cost abundant energy source that can be used as an alternative to our current power grids. Over the years, wind energy production prices have gone down considerably thereby making it a cheap viable renewable energy source. The cost of generating electricity from wind comprises of:
Over the years, technological advances have made it possible to achieve large economies of scale, with larger turbines and plant size, more grid friendly power electronics, and cost

Renewable energy is the energy that is generated from such natural resources as wind, rain, sunlight, geothermal heat and tides that can be replenished naturally. Approximately 16% of all energy that was consumed in the world was generated from these renewable sources. 3% came from new renewables like small hydro, wind and bio fuels
The essay describes main renewable energy sources - wind energy, solar energy, geothermal energy, hydroelectric power, and biomasses. The shortage of fossil fuels is a great problem now, therefore it also analyzes the problems and disadvantages of renewable energy sources usage and if they can be used in order to replace the older ones.
The types of renewable energy include solar, wind, hydroelectric and wave power. Introduction Energy is the main driving force of nature and human civilization. The world is even known to have a high level of energy consumptions which even increased during the industrial revolution.
Arguably, energy is an indispensable prerequisite for causing change or performing work. Renewable and none-renewable forms of energy are the two known forms of energy that have been in use for century. The none-renewable energy source is the natural energy source that is in limited supply.
The recent issue of the Independent newspaper states, that 'British people waste more energy than the inhabitants of any other major Western European nation, hastening climate change and adding 2.5bn to annual fuel bills according to research'. (Hickman, 2006) It means that for Britain the problem of developing the renewable sources of energy and the technologies for their domestic use acquire special meaning and should be thoroughly considered.
2. Assess the suitability of the most appropriately oriented part of your roof for installing a solar water heater. How will this affect the performance of the proposed solar water heaters (If you live in an apartment with a flat roof I guess you'll have to pretend that you live on the top floor!
