Prior to industrialization the main source of energy as was sunlight, other forms of energy were wood, straw, dried cow dung etc. and these resources were infinite (Union of Concerned Scientists; 2017). For transportation muscle energy of horses was used, in the sea wind was used on sails to drive ships also water and wind was utilized to drive simple machines i.e. to pump underground water. Union of Concerned Scientists (2017) further stipulates that simple machines with power to harness steam were
mid 19th century, nearly all energy was used is renewable. Renewable energy is generally defined as energy that comes from resources which are naturally reproduced on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. The oldest known use of renewable energy is the use of biomass to fuel fire 790,000 years ago and harnessing the wind in order to drive ships over water. During the mid-1800s, wood supplied nearly all of the nation’s energy needs, as more consumers began
Renewable energy uses natural resources such as the sun and water to generate sufficient energy whenever it is required whereas the non-renewable energy is taken from sources that are available on earth in limited quantity such as oil and gas. Like Abu Dhabi, Brunei Darussalam depends largely on oil and gas reserves for the survival of its economy but with the continuous usage of the oil and gas resources, Brunei will face a depletion which Brunei then began to follow the footsteps of Abu Dhabi which
Argument The use of fossil fuels has contributed to an increase in global warming. This has made it necessary for other options of energy to be explored. One of the options that have proved to be effective is nuclear energy. This kind of energy is associated with lower emission of greenhouse gas and is renewable. Despite these advantages, the waste produced by nuclear energy has raised concerns. This waste has harmful radiation and it is difficult to store it safely. Nuclear waste is thus a highly controversial

are getting destroyed and yet we are the ones saying we want to stop. Climate change is a change in Earth's climate. This could be a change in Earth's normal temperature. Or it could be a change in where rain and snow regularly fall on Earth. This essay will disscuss the causes, effects and the different ways we can stop climate change. Climate change is having over whelming effects on the planet. It has greatly impacted sea levels. Sea levels and oceans are becoming warming over periods of time
The emphasizing on the emission of greenhouse gas and increased cost of energy have set off a goods and services development which helps individuals and organizations to diminish or balance the emissions and reduce costs. For instance, it has been seen a sudden increase in selling of green household appliances, the designs of
the collective security of everyone within the planet. Security in this context implies the freedom to live a safe life inside a peaceful environment without harmful interference. Considering that every region has its own security challenge, this essay will discuss three security challenges present within Asia Pacific region and also within global community.

Introduction With the growing number of green charities and great effort on teaching people about the environmental conservation, we are now more familiar with this topic. Many scientists contribute the weird climate and frequent natural disasters to climate change or more precisely to global warming. To make improvement on this precarious situation, many nations have got meetings to discuss how to address this big problem and finally reach an agreement to cut down on the carbon dioxide emission
The aim of this essay is to evaluate two contradictory models of ideal urban form: the compact city model and the dispersed city model as contribution to sustainable development and examine whether the two ideas that have evolved in developing countries in the West have any relevance in the context of Southeast Asia. The cities in Southeast Asia are currently subjecting to rapid urbanisation and expansion. Through the case study of Jakarta, the essay will evaluate upon three major aspects namely
