Graph 1 demonstrates the cost of generating 1 kWh of electricity from eight types of power generations. Producing power from solar energy is the most expensive. This is due to the fact that solar panels are highly priced, making solar energy generation the most costly. Following solar energy is petroleum, which is the most expensive fossil fuel energy to generate because it is laborious to pump. The cheapest to produce is natural gas; with the reason being that the technologies for drilling and cracking is advanced.

2.3 Background (Page 2)
An electricity pool market is an organisation that allows the purchases and sales of electricity to take place. As there are many types of energy sources, the way in which electricity is put online is determined by merit order. Merit order is a mechanism which dispatches the energy with lowest marginal energy cost first. System marginal price (SMP) is the value at the equilibrium point between demand and supply, and is the amount that will be charged on customers and companies.
2.4 Theory (Page 2)
Capital cost for solar PVs is high owing to high values of PV cells. However, offshore wind energy has a higher start up price due to the expenses involved in constructing its systems along with the protections needed. Capital cost of onshore wind farms is lower as they are more dynamic and economical to construct. Gas technologies have lower start up amount than coal on account of their low requirement for land space [6]. In addition, expenditures involved in the manufacture of coal fired units are high

In contrast, it will rise for gas and coal as they emit carbon dioxide. Consequently, fossil fuel generations will be pushed out of merit and the market as a result of their high generation costs. For this reason, SMP will reduce because most or all RE units will be in merit since they have zero marginal energy cost.
It is unlikely that changes in fossil fuel values will affect the generation cost of RE. The founder of Bloomberg New Energy Finance (BNEF), Michael Liebreich, stated that the world is deviating to RE so there will be significant development of RE larger than that of gas and coal [9]. A boost in fossil fuel values will gain the energy generation cost of both gas and coal thus there will be more investments in RE generation, which in turn will cut down SMP. Contrarily, supposing there was a raise in the value of fossil fuels, their energy generation cost will decrease resulting in a gain of the SMP.
2.5 Methodology (Page
Renewable energies may cost a little more than fracking but the difference is that they cause less damage to the environment and our health. Funnily enough renewable energies have stopped being researched in the past few years because of fracking.
These sources of energy have a great upside, but right now are incredibly inefficient compared with fossil fuels because of the lack of funding and worldly push (2009). If there isn’t a bigger investment in these alternative energies, fossil fuels are going to maintain their stranglehold on all the economies of the world (Lomborg, 2009).
With any potential energy source initial costs are not the whole picture, potential is a
Renewable energy’s increasingly greater power output has “made wind and solar more competitive with fossil fuels in many regions” (Warrick). In fact, renewable energy has improved so much, both financially and technologically, that many “developing economies will ultimately choose renewables over cheap coal”, enabling them to “skip over a generation of technology” (Warrick). Hydropower, geothermal energy, solar energy, and wind energy will only keep improving in power output until they inevitably become the best choice for electricity. Now that private tech companies have begun to back renewables, their technology is increasing at an extraordinary pace. With more prominent business leaders supporting renewables, the public is more inclined to accept them. People like Elon Musk, CEO of Tesla (and many other companies), fund and promote clean energy projects to raise popular support and develop new renewable technologies. Some people argue, however that renewable energy will never produce enough energy to power the entire United States. After all, “by 2016, wind energy accounted for just over 6.7 percent of U.S. electricity production” and solar energy sits at just “0.6 percent” (Renewable). While this number seems extremely low, it has been increasing rapidly. In 2012, “solar energy accounted for only 0.2 percent of the electricity
While this is great to the consumer, the renewable sector’s growth was more stagnant. Attention was diverted to use another greenhouse producing fossil fuel rather than a clean renewable. A trend in U.S. Energy Information Administration’s (2017) data showed renewable sector’s power production since 2008 grew only 5.7% as compared to natural gas production 18%. Another disadvantage to the diversion from renewables is the additional carbon dioxide generated from these additional plants operating. “About 24 percent of U.S. carbon dioxide emissions are related to natural gas in 2011” (Natural gas prices. (n.d.)). The replacement of coal-fired power plants with natural gas has let to a decrease of the green house gases, mainly particulate matter and sulfur dioxide emissions. “Sulfur dioxide (SO2) emissions produced in the generation of electricity at power plants in the United States declined by 73% from 2006 to 2015, a much larger reduction than the 32% decrease in coal-fired electricity generation over that period.” U.S. Energy Information Administration (2017). This shows that more efficient control equipment can be used to almost eliminate the trace amounts of sulfur dioxide in natural gas.
With the carbon emission regulations recently introduced by US government, natural gas is the most likely substitution to coal for electricity generation for years to come. Latest price reductions made natural gas from a cost perspective much more attractive than coal.
Converting these resources into usable energy requires money. Money is required to obtain them, to ship them, and to convert them. This conversion costs money to build the equipment for converting it, money for parts when something breaks, to maintain it, and to clean the equipment. Some parts cost a substantial amount of money to make or in some cases ship in. As one can see, non-renewable energy resources are expensive.

that producing energy from solar photovoltaic (PV) is the most expensive, with a cost of 21.1 ¢/kWh due to the high prices of solar panels. Contrarily, the least priced renewable energy to generate is hydropower at 8.6 ¢/kWh considering dams require very low maintenance and can last up to 50 years. Petroleum is the most costly fossil fuel to generate, amounting at 12.5 ¢/kWh because petroleum is laborious to pump. Natural gas offers the lowest generation cost of 6.6 ¢/kWh, with the reason being that the technologies for drilling and cracking is
Firstly, and put very simply, fossil fuels are non-renewable! Once the finite deposits of brown and black coal are exhausted around the planet there will be no more energy generated by this process. Current estimates predict that all known coal deposits will be exhausted within the next 120 years.
Renewable energy can be more affordable to people in the U.S. There are many possible ways it can be more affordable. For example, a renewable energy such as electricity can power automobiles with a be less expensive cost than to power it on fuel. Since fuel is related with international market, the price on fuel often result to inflation and deflation (Leistikow n. pag.). According to the chart on Gasoline vs. eGallon prices, Dan Leistikow compares, “Fueling your car with gasoline costs roughly 3 times more than fueling with electricity” (n.
Between 1990-91 and 1995-96, total fossil fuel subsidies in 14 developing countries that account for 25 percent of global carbon emissions from industrial sources declined 45 percent, from $60 billion to about $33 billion)…Within the past six years, India, Mexico, South Africa, Saudi Arabia, and Brazil also cut fossil fuel subsidies significantly…Many developing countries are also actively promoting energy efficiency and renewable energy.
Geothermal Energy The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons.
Renewable energy in its various forms can be over 5 times more expensive than conventional types of fossil fuel forms of energy generation and none are
While wind power is currently more expensive per unit of energy (the initial cost of construction is spread across a turbine’s lifetime, generally around 20-30 years) than alternatives such as coal; wind power lacks the negative externalities that other energy
