Yes, I'm a little late. Sorry! First, let's take a look at the different options we have for alternative or renewable energy sources. NOTE: unless otherwise stated, all quotes are from Wikipedia.
Solar Energy
Use of this energy resource has existed since the time of the "early Greeks, Native Americans and Chinese" who positioned their housing to effectively use the sun to warm the interior.
Uses of Solar Energy
Solar Lighting
Light from the sun is collected via specific window types, sizes and orientation to provide lighting within residential or commercial buildings. This is called daylighting. Hybrid Solar Lighting (HSL) collects sunlight using mirrors "that track the sun. The collected light is transmitted via optical fibers into a building's interior to supplement conventional lighting".
Solar Thermal
"Solar thermal applications make up the most widely used category of solar energy technology. These technologies use heat from the sun for water and space heating, ventilation, industrial process heat, cooking, water distillation and disinfection, and many other applications."
Electricity
Electricity is generated in many ways but most commonly using Photovoltaics. This fancy term applies to that solar cell on your calculator as well as those solar panels used at a large plant.
Sunshine to Petrol
From Sandia.gov: "... intended to chemically reenergize carbon dioxide into carbon monoxide, which ultimately could become the building block to synthesize a liquid combustible fuel”. Is that enough to make your brain hurt? Try reading the rest of the article. :)
Wind Energy
The most common use of wind to create power are the wind turbines I'm sure everyone has seen at some point or not either in photos, on television or in movies. If not, this link has some examples. This type of energy is used widely in Europe and believe it or not the United States appears to be a large supporter of investing in this technology.
Uses of Wind Energy
Wind power can be used to "crush grain or to pump water" or be "connected to electrical grids, as well as in individual turbines for providing electricity to isolated locations."
Negative Effects
Those who are against using Wind Energy cite the other negative environmental effects it causes. To install a wind farm, you must have a large piece of land due the size of them and the required spacing between them. Apparently, there is some argument as to the number of birds and bats killed by the turbines that lie within their migratory path. In Ireland, the pollution caused construction of a wind farm is attributed to the massive amounts of fish dying in a nearby river. The noise caused by offshore turbines might cause harm to sea mammals especially larger creatures such as whales.
Water Power (Hydropower)
This type of energy resource has also been used for a very long time. Think of one of those old mills where the big wheel outside of the building that used the river next to it. Effective, clean power.
Uses of Hydropower
Hydroelectric
Hydroelectric power is generated from dams, think Hoover Dam. This type of power source is widely used across the globe.
Tidal Power
Using water harnessed from tides, this type of power uses turbines sort of like the wind turbines do to generate energy.
Wave Power
Wave Power is more theory right now than actuality. This theory is being put to test in Australia at Port Kembla. This type of power uses generators to harness energy from surface ocean waves.
BioFuel
I’m simply going to put a link to Wikipedia for this one. There’s a lot for it and I’m running short on time.
Nuclear

CANDIDATES’ VIEW ON THIS TOPIC
This has all been paraphrased from the individual candidate's web site. To find out more, click on their name and it will take you to their Environment or Energy page.
Hillary Clinton
Agenda includes reducing carbon emissions, enacting standards which will reduce electricity consumption by businesses, invest in green industries, and increase appliance efficiency standards. Improve emissions standards for federal buildings. Introduce “Connie Mae” program so low to middle income families can invest and purchase “green” housing.
Barack Obama
Agenda includes reducing carbon emissions, rewarding forest owners/farmers, invest in clean energy industry, and support next generation biofuel such as Ethanol and increase fuel economy standards. Make U.S. at the forefront of clean energy investment and technology and of course, reduce dependence on foreign oil.
John McCain
Agenda includes limiting carbon emissions, investing in nuclear energy, reduce dependence on foreign oil. He didn’t really have that much on his site. There seems to be more for him within the site I mention below (The League of Conservation Voters) that they’ve gathered from speeches and press releases and such.
Mike Huckabee
Agenda includes energy independence, pursuing all venues of alternative energy.
Ron Paul
Agenda includes no subsidizing logging in National Forests, encourage development of sustainable energy sources such as solar and wind power, ending government funded projects that harm the environment.
I didn’t get to read through all of the candidate’s material on this and tried to pick out the highlights of their positions on this issue. However, you can go to each of their sites by clicking on their name or use this really good link which sums up each candidate’s Environmental position: http://www.lcv.org/voterguide/
No soapbox on this one people. I’m still exhausted. Take care!

I see a common thread - reduce carbon emissions. sounds great! let's do that! :-/
