By having these renewable energy mandates, it forces certain states to have their electricity generated by renewables, which is a great start for the United States to turn towards clean energy. Along with renewable energy mandates, there is “the federal investment tax credit, which offers a 30 percent credit for facilities that come online by the end of 2020” (Levitan 1). This provides another incentive to continue building renewable sources because the companies will be getting some money back for their hard effort. However, if the investment tax gets discontinued, companies may stop building these renewable sources because they will not get a financial reward. However, with the renewable energy mandate in place, companies might have
We have used biomass energy, also known as bioenergy for thousands of years. In November 2006, hydro was the most widely used renewable energy fuel for electricity production in the United States, following that came biomass. In 2010, biomass provided about 4% of the energy used in the US.Out of this 4% of biomass energy, about 46% was from wood and wood-derived biomass, bout 43% was from biofuels, lastly, about 11% was from municipal waste. Although biomass energy is a really helpful and renewable energy, it cannot solve global warming issues because we need to burn materials in the process. Nobody really noticed things about biomass power until recently, it started to produce large amount of energy comparing to wind energy and solar energy.
The wind power was later designed by Professor James Blyth of Anderson’s College in Scotland. One of the reasons they came up with this idea is because humans rely too much on fossil fuels which increased risk of environmental damage rapidly. They had an urge to develop a clean fuel source that does not pollute the air and they chose to do it with wind power. Unlike coal, wind turbines don 't create greenhouse gases and are a completely renewable source. Today, over 83 countries make use of wind power, with Denmark receiving 40% of their electricity from wind farms.
About 70-90% of the well of shale oil drained in its the first year of extraction and the rest of it drained over 5 years later and thus the age of shale oil wells is considered very short compared to the conventional oil-drilling wells that last for up to 25-30 years, add to this that the shale oil does not have associated gas while there are significantly amounts of associated gas during the conventional oil extraction. And thus the associated gas can be used in investments in the field of energy such as in power generation operations. So it can be said that investment in the field of conventional oil drilling has much more return in investment than the shale oil hydraulic
New homes require far less energy to run than older properties, but building them generates plenty of CO2 (Berners-Lee, Mike). Taking into consideration that it will depend on all kinds of things – including, of course, the size of the house and the types of materials chosen. Also, “the commercial and residential building sector accounts for 39% of CO2 emissions in the United States per year” ("Buildings and Climate Change."). Most of these emissions come from the combustion of fossil fuels to provide heating, cooling and lighting, and to power appliances and electrical equipment. At least in counterpart old houses and new buildings are now being transformed to be more energy-efficient and climate-friendly, so the building sector can play a major role in reducing the threat of Climate Change.
Even though enhanced oil recovery obtains more oil than primary and secondary recovery, its techniques are not used with every oil well because of increased costs. The thermal recovery technique of enhanced oil recovery as its name indicates uses heat to increase the oil recovery. Often steam is injected into the oil reservoir, and its heat will cause the oil to become less viscous. This thinner oil will flow more easily, which enhances the recovery. Almost half of all enhanced oil recovery in the United States uses this technique.
Fig 2. Renewable and non-renewable Energy Sources 1.2.1 FOSSIL FUELS Fossil fuels form the crux of energy use in the world today. 70% of the energy production and 98% of the vehicles on road are run on fossil fuels. There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – hence the name fossil fuels, from about 360 to 286 million years ago.
Especially, renewable energy industry can create more jobs. "Compared with fossil fuel technologies, which is mechanized and capital intensive, the renewable energy industry is more labor-intensive", according to UCS (“Benefits of Renewable Energy Use”, n.d., para. 15). Consequently, the more renewable energy is used, the more the unemployment rate will decrease. In 2011, the wind energy industry employed 75,000 employees in a variety of capacities, including manufacturing, project development, construction and turbine installation, operations and maintenance, transportation and logistics, and financial, legal, and consulting services.
Comparable to other high-end materials, the price of metal roofing ranges from between $150 and $600 per 100 sq ft. But the good news is that the price doesn 't necessarily make this material the priciest option. You get back what you put in if you stay in the house for a long period of your time, and may plan on moving in the near future. Also When you are ready to install a new metal roofing system the initial cost may be off putting, but it is important to remember that this is a long term investment. These roofing systems can last for decades and will require very little maintenance during it 's life cycle.
Pakistan is a developing country day by day, and also facing poverty problems , nearly majority of Pakistan lives in below the poverty-line. According to UNDP- human development report (2008), Pakistan has been 136th position from 177 developing-countries. Nearly, 73% people struggling less than 2 dollar per day. If we position of the Asian countries on earning-poverty, Pakistan offer in last from all the Asian states. Throughout the last ten years ,Government of Pakistan spent compareingtrillions-rupees for poverty reduces programs.
