By harnessing energy from the sun, dependence on more environmentally harmful sources as oil and coal can be decreased.This is a great alternative to these nonrenewable resources. Solar energy reduces the destruction of pristine forests.These forest make carbon dioxide to
Of course, with a clear “green” label, you could easily find yourself in a more premium segment without having to spend as much as the conventional competition. Thus, as a business owner, you need to strongly consider making your tourist hot-spot a more sustainable destination. Here are five basic steps that any resort, hotel, or tourist destination could take to become environmentally friendly. 1. Reduce Your Environmental Impact Investing in energy-saving lighting options, such as CFLs or LEDs, can greatly reduce your energy bills with no inconvenience to your customers.
Drying food out inhibits bacteria from growing so spoilage does not happen for upwards to ten years. That is why drying was so vital in so many places before other inventions like a refrigerator were made or the preservation method of canning was popularized. Many found its uses necessary for survival, as well as long journeys or cold winters where food was nearly impossible to find. Dehydrating food is traditionally done by using the sun or an oven, but inventions like a food dehydrator and other practical appliances like a microwave and toaster oven have made it much more faster and easier to dry out food. Finally, dehydrating food is cost beneficial and greener to do.
Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely. The world pollution is getting worse. Any effort that can reduce the pollution to the environment helps to save the earth. Solar panels can harness the energy from the sun and convert it to electricity. Therefore, the use of solar panels is environment friendly.
In order to decrease the utilization of non-renewable energies to provide largeamount energy, one of the least complex methods to use the energy of sun is photovoltaic panels. Photovoltaic technologies must be sufficiently enhancing that can bemanufactured in huge scale, inexpensive and most noteworthy proficiency.There is a growing need for energy in the world and since the traditional energy sources based on the fossil fuels are limited and will be exhausted in future, PV solar energy is considered a promising energy source candidate. Large-scale application of PV solar energy will also contribute to the diversification of energy sources resulting in more equal distribution of energy sources in the world. The first practical use of solar cells was the generation of electricity on the orbiting satellite Vanguard 1 in 1958. These first solar cells were made from single crystal silicon wafers and had efficiency of 6 % .
Of course the solar energy have some disadvantages too, but it contains quite of advantages also or few more. Solar energy is sustainable sources as long as sun exists, it is renewable, it does not pollute environment and nature, and it has low maintenance. So sun energy should become our main source of producing electricity. Solar energy works with solar panels. Solar panels are made of photovoltaic cells, what convert sunlight into direct current electricity throughout the day.
2.0 Chapter 2 2.1 Sustainable Development in Construction 2.1.1 Definition Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs (McNeill, 2000). Also, a sustainable development should decrease recent levels of consumption of energy and resources and making of waste in order not to damage the natural systems which future generations would rely on to provide them with resources, take in their waste and provide safety and more healthful living conditions. 2.1.2 Importance of Sustainable Development Sustainable development consists passing on to future generations a stockpile of ‘capital’ that is at least as big as the one that our individual
Renewable Energy is practically infinite if it manage properly also it mitigates climate change and foster sustainable development. Renewable energy in the Philippines can support the government’s goal of energy self-sufficiency and sustainability and climate change will lessen. In terms of economic and local development of the Philippines renewable energy can leads to avoided fuel costs, promotes rural and off-grid development, and also savings in health and welfare costs due to less air pollution. The government has taken steps to mitigate the power supply situation by prioritizing the development of the country’s indigenous renewable energy resources. Renewable Energy Management Bureau Assistant Director Marissa Cerezo briefed the Philippine National Bank (PNB) Board of Directors on the renewable energy industry.
(Pant & Others 2012). Energy sustainability with respect to the utilization of availability. Today, sustainable development, including the context of special concern of global warming on the ethical framework, the other is also very important. These include environmental impacts and waste issues, even if they have no environmental impact, security is also a problem. Sustainable development criteria have been pushed to the forefront of energy policy.
Heat generation: In the same way as natural gas, bio gas can be used for household applications such as cooking and heating. Compared with other renewable heat sources biogas is one of the more costly fuels, however, it offers to operate an existing natural gas heating system with green energy. Reduces greenhouse effect: It does not produce any toxic gases which are responsible for green house effect. On the other hand it uses the waste as feed to produce an environmental friendly
