Sustainability and Renewable Technologies Essay

Sustainability and Renewable Technologies - Essay ExampleTrees hold energy tapped from the sun to fix blow in the wood in a natural right smart and therefore be sustainable so long as harvesting can be through 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 absorbed by growing trees. Wood is withal a clean and safe compared to other fogey 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 slight than 1% which can be re apply for other purposes. It will also benefit the social welfare of the broad(a) 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 technology is that it has higher initial capital cost than customary heating systems but in the buildings life-cycle costs. 2.0 Solar Powered Lighting System drop of photovoltaic cells in the building is one of the ways the gild could use renewable energy sources for its routine without leaving a carbon foot print. This is because solar former 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 within 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 enjo y cost 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 even 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 actually 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 region 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 efficiency is dependant on the full exposure of the sun and may affect cloud y days. 3.0 Green Roof The company could consider using a putting surface roof for the building. This is simply having a design that will ensure the entire roof of the proposed building would be cover 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
