  • Renewable Energy Resources: Solar Energy

    1951 Words  | 8 Pages

    Solar energy is a fast growing energy resource among the renewable energy resources in the market and potential for solar power is huge to contribute towards the power demand almost in all the countries. The solar irradiation and temperature are mainly depends on the output power produced from the PV conversion process. Hence the maximum power point of PV array is tracked to maximize the efficiency of Photovoltaic system. Maximum power point tracking (MPPT) control system in general is taking care

  • Energy Resource: Coal and Solar Energy

    1822 Words  | 8 Pages

    imagine not being able to plug your cell phone in to charge, or use the microwave, or turn on any lights? These would all not be possible without electricity. Electricity can be produced in many ways. Two ways are through coal and solar energy. The way these two energy sources are produced and the effects they have on the environment are very different but they are both used to produce electricity. Coal is one the fossil fuels in this world. There are four main types of coal. Anthracite, bituminous

  • Energy Resource: Natural Gas and Solar Energy

    1231 Words  | 5 Pages

    My two topics that I will be talking about are Natural Gas and Solar Energy. Natural gas is a nonrenewable resource and pretty soon we are going to have to learn how to do without it. Solar energy will always be around. It’s not very major now but in a few years I’m sure it will be. Natural gas is a mixture of Hydrocarbon gases that form with a petroleum deposit. A hydrocarbon is a compound that’s mostly made up of Hydrogen and Carbon. Natural gas is methane together with some of ethane, propane

  • Advantages Of Renewable Energy Resources

    894 Words  | 4 Pages

    demand for energy; that is the ability to do work or in other words move the machinery, become intense. Driven by the profit, and with little or no knowledge about the damage caused by the combustion of the fossil fuels the humans started to use massively this nonrenewable source of energy, mainly the coal. Nowadays we are suffering from climatic changes caused by intense burning of fossil fuel, however this scenario can change with the growth of the usage of energy generated by renewable energy resources

  • Energy Resources: Fossil Fuels to Biofuels

    948 Words  | 4 Pages

    What do you use for fuel? It is probably is gasoline or diesel. Well, there is another source of fuel, and it is renewable. Biofuels are fuel made of organic material, and where energy is produced from plants. One biofuel, ethanol, could eventually replace gasoline (petroleum). Biofuels are a cleaner energy than fossil fuels, but there are advantages and disadvantages for both biofuels and fossil fuels. Biofuels contain carbon, hydrogen, and oxygen. Organic material like vegetable oil can be used

  • Kerogen Types and Unconventional Energy Resources

    3295 Words  | 14 Pages

    and gas and which types of unconventional resources it can form. It makes up four different types that are each prone to mature into a certain form of petroleum product. Type I is dominantly oil prone, Type II can generate both oil and gas, and Type II is mainly a gas generating kerogen. Type IV is considered “dead oil” and does not generate any producible hydrocarbon. The three main producible types can be seen in many different unconventional resources in which this report discusses some of the

  • Overview of Ecology Topics: Energy Flux, Food Webs and Resources

    1399 Words  | 6 Pages

    Energy Flux in Ecological Systems The concept of ecology considers interactions between organisms and their environment across several scales of analysis. Population ecology includes investigations of the physiological principles that modulate how individuals interact with their environment, and resource competition theory that explores the dynamics of both individual and interacting species. Community ecology focuses on large assemblages of species and considers how in fluxes of matter and energy

  • Advantages And Disadvantages Of Solar Power

    1072 Words  | 5 Pages

    essentially the conversion of the energy from the sun to usable electricity. The most common source of solar power utilizes photovoltaic cells to convert sunlight into electricity. These photovoltaic cells utilize a semi-conductor to absorb the radiation from the sun and when the semi-conductor absorbs this radiation it emits electrons, which are harnessed as electricity. The picture on the right depicts a similar setup to the same way the home rooftop solarpanels work. Energy is harvested from the sun and

  • China

    1619 Words  | 7 Pages

    say now resembles that of a “nuclear winter” , we’ll attempt to critically evaluate the issue of air pollution and natural resource consumption, discussing any related policy proposals within China, and weighing both the costs and benefits of either unregulated or ecologically conscious economic expansion. By examining the issue of Chinese air pollution and natural resource consumption we’ll be better equipped to answer the question of whether larger scale, global economic development will have any

  • Towards a sustainable energy supply: Shifting paradigms in energy supply

    1050 Words  | 5 Pages

    Following Hubbert (1956) and his Peak Oil theory, there was a remarkable increase in the efforts made by the environmentalist to find replacements to oil as a way of satisfying the world energy demands, but one century before nearly all energy already came from renewable sources. Even when the first use of biomass for fire is well documented several hundreds of years ago, it is widely accepted that its use did not become common until much later. Related to sustainability measures to reduce the
