renewable energy system. Because of abundant availability of solar energy recently the solar power generation systems are getting more attention, more efficient and more environment friendly as compared to the conventional power generation systems such as fossil fuel, coal or nuclear energy. Photovoltaic cells are devices that absorb sunlight and convert that solar energy into electrical

limited in reserves and highly concentrated in certain parts of the globe. Those countries not having these resources are facing energy / foreign exchange crisis due to heavy import bill on crude petroleum. Increased extraction and consumption of fossil fuels have led to a fast depletion in the underground-based petroleum derived fuels. These factors have contributed to a sharp increase in petroleum prices. Also, the petroleum fuels are currently the dominant global source of CO2 emissions, Green

Brunei is produced by gas-fired power stations in which the resources come from the use of fossil fuels. When fossil fuels are used, they release carbon dioxide, nitrogen dioxide, sulphur dioxide, carbon monoxide and others as well. This is one of the causes for increase in global warming, thus, responsible for climate changes. They are one of the energy sources that are non-renewable as they come from the fossils that will no longer be available once we use them up. The supplies are limited and they

The change of climate of the planet’s surface leads to the problem of greenhouse gases which “account for around 98% of the environmental pressure leading to climate change. They are: nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). The activity of these gases leas to the Global Warming Effect, as all three of them are able to trap heat in the atmosphere. The danger lies in the Earth’s rising temperature, which makes the glaciers melt. All the energy that turns out to being the atmosphere

CHAPTER-6 REFRIGERATION CYCLE Figure shows schematic diagram of vapour absorption refrigeration system. In this system we use flat plate solar collector as source of heat energy and that heat energy will have used in generator. PROCESS: 7-1Generator is main component of our cycle and in the generator weak solution of LiBr and water is coming from absorber. This weak solution gets heated in Generator and the generated vapour having high temperature and high pressure is supplied to condenser.

Climate change is refers to the rise in average surface temperatures on earth, mostly due to the burning of the fossil fuels such as oil and coal, which emits greenhouse gases into the atmosphere which are primarily carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons (#02). In addition, other human activities, such as agriculture and deforestation, also contribute to the growth of greenhouse gases that cause climate change (#01). According to this, many have make their own

Have you ever wondered why in areas where’s it’s typically hot its now become colder, and in areas where it’s typically cold it’s now become warmer. For many year now, people have wondered if global warming is a true topic to be worried about. Throughout the years, the world has encountered people who believe that global warming is natural, and that the temperatures change over time regardless of human interference. On the other hand, there are people who believe that global warming is very serious

introduced to the heater or furnace. In the furnace the stream is heated to 600 °C, the reaction temperature, then introduced into the reactor. The reactor is where the main reaction happens: C7H8 + H2 C6H6 + CH4 This reaction is irreversible, and it requires catalyst. The catalyst consists of chromium or molybdenum oxides, platinum or platinum oxides, on silica or alumina. The catalytic process occurs at lower temperatures and offers higher selectivity but requires frequent regeneration of the

Electricity: The basic thing that government can do is to solve the power crisis in pakistan.Electricity production is necessary for our industry. From the last decade energy crisis totally ruined the Pakistan economy so government should take necassy steps for solving energy crisis problems in pakistan.Dams should be built on emergency basis.Government have to complete kala Bagh dam project because kala bagh can fulfill our electricity crisis to some extent.In Pakistan summers are very hot so solar
