Renewable Energy Policy Important to Future of Planet
Renewable Energy Policy Important to Future of Planet, but more importantly, to mankind's future
Most recently, at Obama’s 2012 State of the Union Address Energy, he laid out a half dozen energy proposals, however, most of the policies he announced were either previously announced, stand little chance of passing through congress, or not that big of a deal. According to Jose Valera, a Houston based lawyer in the energy practice at the global law firm Mayer Brown, “It’s a smart, well balanced, welcome policy, and everybody is a winner.”
While the traditional fossil fuels will still play an important role in the future while we transition to renewables, in technologies like wind and solar, Obama called for extending tax credits that basically give these firms a 30% subsidy and also called for the federal government to allow renewable projects on its land.

Clean Energy Fuel What Are They?
Clean energy fuel definitions can greatly vary depending on who you ask
Methane (CH₄) is a primary component of natural gas and a highly potent greenhouse gas which can also be emitted into the air when the gas is not burned properly and completely. Similarly, methane can be emitted as the result of leaks and losses during transportation. Emissions of sulfur dioxide and mercury compounds from burning natural gas are negligible.
Methane remains in the atmosphere for approximately 9-15 years and is 25 times more effective in trapping heat in the atmosphere than carbon dioxide (CO₂) over a 100-year period and 72 times more potent over a 20 year period. It is emitted from a variety of natural and human-influenced sources. The human-influenced sources include landfills, natural gas and petroleum systems, agricultural activities, coal mining, stationary and mobile combustion, waste-water treatment, and certain industrial processes.

Offshore Wind Power Important to Future of Clean Energy Development
Offshore Wind Power Important to Future of Clean Energy Development Like This Horns Rev from DONG Energy in Denmark
The problem with these projects is that they tend to be expensive, costing roughly 2.5 to 3.0 million Euro/MW. The turbines themselves represent only a third to one half of the total costs in the projects today while the rest of the costs come from the infrastructure required, maintenance and oversight of the projects. In 2011, Danish energy company DONG Energy made a claim that these types of projects aren’t yet competitive with fossil fuels, however they estimate that they will be in 15 years. Until that point is reached, government funding, subsidies and other incentives will be required to make the projects more economically feasible. Taking that into account, we still heavily subsidize the fossil fuel industry so why not shift some of that funding over to these types of projects?

Renewable and Non Renewable Energy Sources Explained
Renewable and Non Renewable Energy Sources Explained
Renewable and non renewable energy sources explained will help you to understand the differences between the two and determine which is better. For this explanation, we are referring to electrical energy or energy to run our vehicles, boats, and other forms of transportation. The two combined are the driving factors behind both our economy and our society as a whole, for without either we would almost be back in the dark ages so to speak.
That day will come when we will be without coal and oil, however there are alternative sources of energy available to us which we are finally beginning to utilize more of. Fossil fuels are not good for the environment so to help protect our planet, it is wise for us to move forward with alternative energy for our future energy needs.

Solar Power Advantages and Disadvantages Explained
Solar Power Advantages and Disadvantages Explained
For starters, the initial costs are expensive, however, Solar Power Prices Are Falling Quickly, and expected to be less expensive than the grid by 2015 in certain locations. Another point to consider as to why solar is not more mainstream yet is that Fossil Fuel Subsidies are six times more than renewable energy, at the least. If all tax breaks and other aid is included in calculating fossil fuel subsidies, that figure is even higher! One good thing to note here, in 2010 the US had a 186% increase from 2007 in US renewable energy subsidies . Even after the Solyndra failure, Obama Stands by Renewable Energy Aid, which shows he is doing what he can to help the environment amidst an increasingly arrogant and anti-environment right wing movement.
