Why is the world unable to detach itself from conventional energy sources?
Pure economics. It costs more to use "non-conventional" energy sources.
How does renewable energy work?
Energy is obtained from renewable energy sources (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and bio-fuel among others) and turned into electrical energy. This electricity is just the same as any other electricity and is used normally. Energy from renewable sources does not produce extra carbon dioxide (global warming) to the carbon cycle and is nearly free after the initial set up and maintenance costs.
Is solar energy safer then nuclear energy?
Solar energy is certainly safer than nuclear energy, but decidedly more expensive with much greater space requirements...at this time. As solar and other alternative energy sources are developed, it is reasonable to assume that the costs will decrease. Whether or not they will ever decrease to the costs per kilowatt hour that nuclear energy can achieve remains to be seen.
What does mean by renewable energy?
A natural resource qualifies as a renewable resource if it is replenished by natural processes at a rate comparable to its rate of consumption by humans or other users. Resources such as solar radiation, tides, and winds are perpetual resources that are in no danger of being used in excess of their long-term availability. Natural resources that qualify as renewable resources include oxygen, fresh water, timber, and biomass. However they can become non-renewable resources if used at a rate greater than the environment's capacity to replenish them. For example, groundwater may be removed from an aquifer at a rate greater than the sustainable recharge. Removal of water from the pore spaces may cause Renewable resources may also include commodities such as wood, paper, and leather. Furthermore alcohol is also a renewable source of energy, similarly,oils from plants and seeds can used as even as a substitute for non-renewable diesel, last but not least methane is also considered as a renewable source of energy. Gasoline, coal, natural gas, diesel and other commodities derived from fossil fuels are non-renewable. Unlike fossil fuels, a renewable resource can have a sustainable yield. i won't change the answer bt i am givin' u a simple and short one........ A renewable resource is one that is replaced by natural processes at a rate that is equal to or faster than its consumption. For example, the wind, the tides, and the sun, are all resources that can be utilized for their power and are in no danger of expiring; These resources will always be available, despite the consumption level. Resources such as water, timber, and geothermal energy must be intensely monitored in order to avoid over-consumption, and thus deprive the resources of their renewability.
What are the capital costs or setup costs involved in using nuclear energy?

How does renewable energy save money?
Energy is not renewable. The sources to make that energy may be. After the initial cost of plant and equipment some sources are practically free so the only costs are maintenance costs..
Why shouldn't you use as much energy?
Using excess energy costs you money; some sources of energy damages the environment; and some sources of energy are non-renewable, meaning that our children or grand-children will have problems getting enough energy, because we squandered it.
Why does the UK not produce all its energy with renewable sources?
This is not just the UK; you have the same situation all over the world. I suppose the main reason would be the costs - renewable energies are often more expensive than the traditional ones.

Why do most people use nonrenewable energy instead of renewable resources?
Cost. If there was an alternative that was cost effective the free market would embrace it. Unfortunately there is no cost effective solution. Hold on to your wallets because the solution will be to raise current energy costs to "level" it with more expensive "renewable" sources.

What are the benefits of green hosting?
Green hosting refers to the process by which a web server company generates or buys the electricity required to run their servers. In green hosting, the energy is from renewable sources. The benefits of green hosting are that it is environmentally friendly, it can improve the reputation and image of the hosting company and any firms using it's services and the are bodies that offer subsidies for using a green host hence reducing web hosting costs.
Is there anything bad about renewable energy?
Costs moreProduces less energy than an nonrenewableThat's all I can come up with, hope it helpt a little :)
What is the renewable energy source?
Solar power and wind.While there are many sources of renewable energy the best sources of renewable large scale sources remain wind energy and some forms of solar power. According to studies presented in 2009 these two sources are the most viable for large scale usage. While the initial installation costs for these energies remaining higher than more traditional sources (coal, fossil fuels, etc.) the costs of the power itself is significantly lower.HydroelectricThere may be some debate as to what is meant by "best". All forms of energy generation will create some form of waste (or pollution). Solar causes the pollution in it's creation and short life span (under thirty years). Wind kills birds and is ineffective when there is minimal wind.The one renewable source we have that offers us power similar to that found from fossil fuel plants though is hydro. Water flows all the time, not on the whim of weather. Thus, we can derive power from hydro on our schedule and not that of the weather, as solar and wind do. Additionally, Hydroelectric is a proven technology with a positive return on investment.
What are some advantages and disadvantages of thermal energy?
There are two main types of thermal energy - solar and geothermal. Solar energy is renewable and sustainable, and after the initial investment, is free. Geothermal energy is renewable, sustainable, and clean reducing reliance on foreign energy sources. The disadvantages are mostly financial because of the start up costs. While solar is an individual form of energy, geothermal requires large generation plants. Also solar viability is dependent on the amount of sunshine the area receives.
Why are fossil fuels used to generate electricity in favor of renewable energy?
The basic reason why is because of infrastructure costs and the unknown. With fossil fuel plants the running and maintenance costs are predictable and because they have been around for such a long time their useful life spans and life cycles are well known. As for renewable and green energy such as solar, it's relatively new compared to fossil fueled plants, not a lot of data on life cycle costs has been gathered as well as very high investment costs have held back many companies from implementing renewable energy. You will expect in the future to see more renewable energy projects such as solar energy as the price of solar panels has dropped dramatically over the last few years and scientists are working on creating liquid batteries to store solar energy when there is no sunlight. The near future for renewable energy is very promising.
