The need for alternative energy sources is getting urgent, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting energy systems. Some of these apparatus are great works and need improving for massive use. Politician’s world-wide are drafting policies and are making agreements to make greater use of these energy sources.

The first problem is that the fossil fuels are depleting in a rapid rate and are harder to retrieve. The consequence is that we can be facing an energy crisis in the future is we are not careful today. The energy prices will sky rocket and not be available for many individuals or countries. To avoid this doom scenario we need to find alternatives and used them to their full potential. Luckily this is already happening.

The second problem is that the fossil fuels that are widely used today are harmful for the environment. In the early seventies and eighties there were people and even scientist who preach otherwise, but today the negative effects are showing. The earth is warming up and climates are changing. There are parts in the world were there be more rain and sunshine and others parts will be come dryer then they already are. Another negative effect is that the ozone layer is getting thinner which also leads to a warming up of the earth. These two effects compliment each other and make it even more crucial to make another step in a different direction. This step will lead us to the use of renewable energy.

Another problem lies in the development of small economies. Because the energy prices for crude oil are going through the roof, these countries suffer even more. Many of these countries need crude oil for their electricity and means of transportation. These high oil prices have their effect on almost everything. The monthly electricity costs for households increase among others like transport cost and prices for basic products. Hence, these high oil prices make it harder for these small countries to grow there economies.

The solution for the above problems can be resolved by renewable energy. Our beautiful planet gives us the opportunity to make proper us of sunlight, flowing water, strong winds, and hot springs and convert these into energy. These energy sources are abundant and free to use. We must be sure that we convert the energy the right way, without causing other problems that can again hurt our environment. Luckily the many efforts by individuals and companies show that this can be done.

I’m writing a paper on alternative energy, and I’m going to talk about how it is a cure for many of the world’s problems. I’m going to mention:
- energy independence
- global warming
- global/national economy

I need one or two more ideas because it has to be a long paper. Basically, I need more things that would be improved if a stronger initiative were taken towards alternative energy expansion.

-National Security.
Wars arise from fighting over this limited resource

-Clean energy if it’s from solar, wind, geothermal, or wave/tidal powered.
Fossil fuels not only puts tons of CO2 in the air, but also particulate matter. You can also branch another benefit off this and say that this will improve the health of society by replacing fossil fuels with alternative energy.

I recently read that it might be possible to drill a hole down into the earth to a depth where the rock is naturally very hot, pump water into the drill hole and then power a turbine with the steam that is created to generate energy. (It’s like a DIY version of electricity generated from natural geysers). It’s clean and can be done almost anywhere. Has anyone heard of this? Is this a viable alternative energy?

yeah its alreay been done but its not diy.

Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.

Electric bills and fuel bills are rising steadily but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient.

In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to go primitive, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment.

Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers.

In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total green energy systems costs.

In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called net metering laws. The rates that they are being paid by the local power companies for this energy are standard retail rates in other words, the homeowners are actually profiting from their own energy production.

Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government, the Energy Department’s Craig Stevens says.

And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. We should [only have to] pay you the wholesale rate for … your electricity, according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy.

However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, It’s quality power that strengthens the grid.
