Bauhaudin, Elias, and Saifudin define the green building as an edifice that has the capacity to “reduce the undesirable human impacts on the natural surroundings, building materials, building assets, and enhances human health and the natural environment” (Bauhaudin et al. 2). In other words, a green or sustainable building is designed with the intention of allowing human beings to co-exist harmoniously with the environment by creating an edifice that is environmentally friendly. However, it should be noted that “the perception of what is a sustainable building is changing over time and depending on the location” ( ...

Global warming is the rise in average global temperatures. The rise in global temperatures is occasioned by the emission of greenhouses gases such as carbon dioxide, carbon monoxide, methane, and nitrogen oxides. The gases are released from industrial process that combust fossil fuels such as diesel, coal, and petrol. Such processes include generation of electrical energy in thermal power stations, burning of coal in industrial boilers, and combustion of fossil fuels in internal combustion engines. When these greenhouse gases are emitted, they rise to upper levels of the atmosphere and form a layer that blankets the earth. This layer ...

Climate change is one of the biggest challenges facing humans. Individual’s lifestyles have developed to such an extent in developed countries that people continue to drain the earth of fossil fuels used to sustain humans. The result is that global warming is happening as a result of natural but predominantly human activities that release carbon emissions into the atmosphere. Measuring the best forms of energy to counteract this depends on a number of technological, economic and societal variables. It also requires the efforts of government to use command and control along with economic incentives to the highest potential for each ...

Gay marriage is part of same sex marriage where the democrat defines it as a union or marriage of people who are of the same sex loving each other. Democrat’s liberal supports the legalization of gay marriage and other types of same sex marriages such as bisexual, lesbian, as well as transgender. This they argue is part of ensuring equal rights to every citizen. They therefore oppose to the constitutional amendment which establish marriage a one woman one man union. They argue that every person has the right to marry regardless of his/her sexual orientation.

Greenhouse gases are those gases that trap heat in the atmosphere. Several chemical compounds in the earth’s atmosphere are greenhouse gases. They allow sunlight to pass through them into the surface of the earth. This light is reflected form the surface back towards the space in the form of infrared radiations or heat. The greenhouse gases absorb these radiations and trap the heat in the atmosphere. After some time, the amount of energy sent from the sun to the surface becomes equal to the energy radiated back into the atmosphere. This process leaves the temperature of the surface ...

Abstract

The universe contains 100 billion galaxies. Each of these galaxies has billions of stars, great gas and dust clouds with others having scads of moons and planets. The stars release an abundance of energy either from radio waves, X-rays or from other forms of energy that run at a speed of light across the universe. However, all that can be seen is like the tip of the cosmic iceberg and accounts for a small portion of the total energy and mass in the universe. About one-quarter portion of the universe is made up of dark matter that does not release any ...

The continued prosperity and economic development of some countries e.g. the first world nations has traditionally been associated with growth in energy production and consumption. Ideally the use of energy is intended to enhance the quality of life. It is becoming apparent that the production and consumption of energy is also responsible for an increasing deterioration of the environment. The imposition of air pollution standards has accelerated a shift in the use of fossil fuels towards those that have clean burning characteristics e.g. low sulphur oils and natural gasses. This in turn has led to worldwide and domestic scarcity ...

The writing is about Nuclear energy and the advantages and disadvantages it offers over other means, ways and sources of power generation like Hydroelectric plants, coal powered power plants etc. The organization pattern being used here is Problem-method-solution, which puts across problems first and then proposes effective and useful solutions. Nuclear energy is a way of creating heat through the fission process of atoms. The power plants covert heat into electricity using steam. (USNRC, 2012). Nuclear energy has been used for quite sometime by many developed and developing countries to meet their power and energy requirements. Like all other ...

The theory of sustainable development is perhaps the most equivocal factor that has dominated many debates in addition to generating equally varied interpretations from environmentalists. Sustainable development places significant importance on the maintenance of natural resources. For this reason, several values often emerge when defining or during the inclusion of natural resources. Resources come in different types that can be categorized as renewable and non-renewable. While resources are useful for the survival of humans both in supporting life and in meeting people’s needs, the satisfaction of human needs and scarcity of resources has led to several resistances. Such ...

Sustainable Energy

Sustainable energy sources are relatively cheap and are infinite, meaning that they would never run dry. Some sources of renewable energy which a sustainable society would draw its energy in the future includes Solar energy, wind and hydropower. Solar energy is the ultimate source of power.
