    It is certain that fossil fuels are likely to be exhausted sooner or later. It is rather satisfying that ‘Fossil Fuels’ sustained the global energy needs till date. Although there were no serious issues of this generation initially, gradual awareness on Environment posed many problems, over the last few decades. This awareness has gained considerable momentum with 'Climate change' in the forefront.

    On June 2, 2014, the Environmental Protection Agency (EPA) issued its Clean Power Proposal for reducing CO2 emissions from existing plants in accordance with Section 111(d) of the Clean Air Act. The agency's goal is to reduce CO2 emissions from existing power plants by 30% from 2005 CO2 emissions levels by 2030.

    The earth is getting warmer. There's no doubt about that. The average temperature of our planet rose 1.4 degrees fahrenheit over the last 100 years, and is expected to continue on that path over the next 100 years. Some are even predicting an increase by as much as 11.5 degrees fahrenheit, and with these temperature changes come environmental changes. Droughts, heat waves, rising sea levels, and melting ice caps are slowly becoming the norm, taking a permanent residence on the back burner instead of where they should be...front and center!

    The 3rd National Climate Assessment (NCA) was recently released, painting a frightening picture of the spiraling costs of climate disruption to America and highlighting the need to price carbon dioxide (CO2) emissions. While President Obama has pledged action and the electricity industry nervously awaits new EPA regulations for power plant emissions, the most appropriate action remains politically impossible: carbon taxes, cap and trade and carbon pricing are all consistently used as divisive issues to excite the conservative base of the GOP.

    The economic and environmental benefits of solar and other clean energy sources are well documented and represent added value for the developed world, where sustainability is considered a lifestyle goal. But in the developing world, sustainability is more often a means to improve quality of life, especially for those living and working in remote areas where grid-delivered electricity is limited, if not completely inaccessible, and conditions of electrical poverty impede social and economic progress.

    It seems persons trying to rid the planet of our conventional fuels; coal, oil and natural gas, will go to great lengths of completely lying. First of all, so-called but misnamed "greenhouse" gases cool the earth - they don't warm it! Also, so-called "green energy" is not green at all!

    In April 2014 the U.S renewables industry made international headlines when the Energy Information Administration's (EIA) monthly figures revealed that the country's solar capacity had increased an unprecedented 418% from 2010 to 2014. Marking the watershed moment, commentators at the EIA stated that 'U.S. solar capacity has moved quickly from a relatively small contributor to the nation's total electric capacity into a one of comparative significance'.

    The technologies described in this series generate electricity when their resource is available not when it is needed. In any power system, the generation must match the demand on a second by second basis. So, to go large-scale, renewable energy needs to find a technology that will store energy efficiently and at a low cost.

    The potential energy in waves is enormous, so it is not surprising that there have been many attempts to use them to generate electricity. But while the potential is there, harnessing it is neither easy nor cheap. It is extremely difficult to design something that will survive a storm and, at the same time, generate electricity efficiently and economically during average wave conditions.

    The current worldwide installed solar capacity is about 40,000 MW of photovoltaic power and about 1,170 MW of concentrated solar power.
