Sustainability and Renewable Technologies Essay

Sustainability and Renewable Technologies - Essay ExampleTrees use energy tapped from the sun to fix carbon in the wood in a natural way and therefore are sustainable so long as harvesting can be make without depleting the woodland resources. Due to its nature wood fuel is virtually carbon neutral as the carbon dioxide emitted from burning is balanced by the carbon negligent by growing trees. Wood is as well as a clean and safe compared to other fossil fuels like oil which are harmful to the environment in case of spills. The wood fuel gas is almost smoke free and its ash content is less than 1% which can be reused for other purposes. It entrust also benefit the social welfare of the entire community in that use of wood would ensure proper management of woodlands and promote local trade. By creating a ready market for wood fuel many jobs would be created to manage and ensure sustainable practice in managing woodland. The main disadvantage of this applied science is that it has h igher initial capital cost than conventional heating systems but in the buildings life-cycle costs. 2.0 Solar Powered Lighting System determination of photovoltaic cells in the building is one of the ways the company could use renewable energy sources for its surgical operation without leaving a carbon foot print. This is because solar business leader does not consume natural resources, are readily available and are naturally replenished. 2.1 How it works The building is laced with light sensitive cells called the photovoltaic cells that convert light from the sun into electrical energy. This electricity is then stored in a battery system that is used to power the lighting system and other appliances indoors the building. A sketch of the system is attached. 2.2 Advantages Using a solar powered lighting system in which solar power is used to generate the electricity for the buildings lighting ensures energy security by reducing dependency on fossil fuel or the national grid. As a result the company will enjoy price stability as photovoltaic cells are installed only once and have lifespan ranging from 20-30 years. With solar power there are no transmission costs as all the energy produced is consumed unlike other sources where the fuels have to be transported. It is therefore ideal sluice for places that cannot have access to the grid. Cost wise the solar panels are becoming cheaper and more efficient thus ensuring more value for money. It is also a rattling quite source of energy which is a great advantage of a service oriented company in which communication is key in its operation and a quiet working environment has a great impact. 2.3 Disadvantages Major disadvantage is the high cost of installation it also requires a large commonwealth for installation. This can however be mitigated by incorporating a building design in which photovoltaic cells are positioned for optimal harvesting. The other disadvantage is that might is dependant on the full exposu re of the sun and may affect cloudy days. 3.0 Green Roof The company could consider using a greens roof for the building. This is simply having a design that will ensure the entire roof of the proposed building would be covered in vegetation to form a sort of living roof. 3.1 How it works The roof is covered with vegetation that is grown over a waterproofing membrane. The membrane helps to prevent percolation of water and also root
