Energy is defined in physics as the capacity to make things move; it is widely used in today people’s residences‚ a variety of industries and technology fields. Most of the energy we use now comes from fossil fuels coal‚ oil and natural gas‚ which are being consumed more rapidly than they are being replaced. That means eventually we will use up these fuels. That is why we as a society need to broaden our research to develop new forms of energy resources are for this happens. There are kinds of

The main hindrance for the penetration and reach of solar PV systems is their low efficiency and high capital cost. “Solar Panel Maximum Power Point Tracker”. As the name implied‚ it is a photovoltaic system that uses the photovoltaic array as a source of electrical power supply and since every photovoltaic (PV) array has an optimum operating point‚ called the maximum power point‚ which varies depending on cell temperature‚ the insolation level and array voltage. A maximum power point tracker (MPPT)

Practitioners of sustainable living often attempt to reduce their “carbon footprint” by altering methods of transportation‚ energy consumption and diet. Proponents of sustainable living aim to conduct their lives in ways that are

1. Introduction Sunrise Square is a newly proposed commercial building‚ aimed to secure the BCA Platinum Green Mark award‚ to be completed by October 2015. The building is fully air-conditioned except for some common areas and it has a multi-storey carpark which is to be naturally or mechanically ventilated. The air-conditioning system for the building is water cooled chilled water system. The cooling load of the system is greater than 500 RT. The purpose of this project is to recommend the

Global Engineering Challenges There are global challenges that engineers face in society from ways to lessen our dependence to oil and protect the environment to ways to improve our surroundings and expand our reality and minds. A lot of these challenges will need engineers with vision and passion in order to come up with the solutions needed to improve the world around them. The three global challenges that will be covered in this paper are ways to lessen fuel consumption‚ how to restore and improve

The earth receives extremely large amounts of energy coming from the sun. Solar energy has become a number one option for a future reliable‚ greener energy source. An article by the National Academy of Engineering‚ Make Solar Energy Economical‚ has proposed this issue as one of the many challenges engineers face this 21st century. The academy emphasizes‚ the sun’s “availability far exceeds any conceivable future energy demands. It is environmentally clean‚ and its energy is transmitted from the sun
