• When there is no sun means at night or because of the cloudy atmosphere, there is no use of this expansive system. • In most of the solar air heaters solar panels are used. So in the performance of this kind of system, the location of solar panel has also a very important roll. • Poor heat transfer properties of the air is also the major disadvantage of this kind of system. • Sometimes it is very hard to handle large volume of air due to low density of the air.
There are also man places in rural Peru that do have the capability for water pipes to be placed that allows water to always be available. Also water cannot be drunk straight from the tab like it can be in the United States. It has too much bacteria and would make a person very ill. Also almost no sunlight can be seen in the major cities of Peru, such as Lima. This is due to the excessive contamination due to the many factories in Peru. The sky looks almost completely gray throughout the entire year and when a person steps outside their clothes have a dirt substance all over them due to the pollution.
To illustrate, water quality in Nairobi is decreased because many industries increased a large amount of fertilizers and pesticides to be used (The World Factbook, n.d.). As a result, People cannot drink water from the river at all nowadays because in the river has a lot of waste, so the water became undrinkable. Furthermore, currently, Kenya’s government cannot solve the problem of public transportations including vehicles that cause bad air pollution . It is because they lack strong
During the year at least once you realize your refrigerator is not working. All your food gets spoiled and you have to call a repairer instantly. Another negative is that refrigerators are slowly hurting the earth. They are not eco-friendly. Refrigerators have a chemical in them called chlorofluorocarbon and when it mixes with the air it hurts earth's ozone layer.
Manufacturing requires significant quantities of fossil fuels, a non-renewable resource. Burning of plastics is releasing smokes which can harm our environment. The smoke contains small particulates, hazardous substances and greenhouse gases that is why it is not advisable to dispose plastics by burning it. Most plastics are not biodegradable and because of that, it can persist in the environment for many years. Plastics can cause blockage of drainage and sewage systems, resulting in water logging, flooding and the spread of water born diseases.
Although the pros are very big there are some cons. Non- fossil fuel energy has a lot of trouble producing the amount that fossil fuels can produce. This means we need to cut down on the amount of energy we use or just build a lot more production facilities. Another downside is that renewable energy relies on weather 90 percent of the time. If there isn 't rain to fill the dam the Hydro generators can 't run.
The plants which are underneath the dam full of water begin to rot, this type of decomposition without oxygen involves giving off a lot of methane and carbon dioxide. Moreover, Even though the maintenance costs of the power plants are pretty low, another negative aspect of building them is the cost, they are generally really expensive. In addition, There is also a really high risk of floods in the lower elevations. There are limited suitable reservoirs in the world for hydroelectric power plants, most of them
This is a country that already faces extreme climatic conditions and has precious natural resources, so long-term imbalance in temperature and precipitation will produce adverse impacts. The UAE is a low lying coastal country with a dry climate, which also faces high temperatures. At the same time, we play a crucial role in the world’s energy economy as a supplier of fossil fuels, which gives us an important stake in finding solutions to cutting emissions while still providing the world with the energy it requires. With financing the renewable energy and the role as the host of the International Renewable Energy Agency (IRENA), we are at the heart of the clean energy innovation. The UAE is active in the fight against climate change both because we acknowledge the risks of not acting and because we are responsible global citizens committed to multilateral action.
In some cases, there is no vegetation in the areas surrounding  the flare due partly to the tremendous heat that is produced and acid nature of soil pH. The effects of the changes  in temperature on crops included stunted growth, scotched plants and such other effects as withered young crops. They  concluded that the soils of the study area are fast losing their fertility and capacity for sustainable agriculture due to the acidification of the soils by the various pollutants associated with gas flaring in the
Due to high illiteracy rates and lack of trainings, rural people lack entrepreneurial skills and knowledge of technology that they need to improve their living standards. The limited access to credits and financial services, increasing cost of goods and services also aggravate poverty in rural areas. The other cause of poverty is natural calamities. According to Wangdi (2015) since Bhutan lies in a mountainous region, our ecosystem is very fragile and prone to impact of climate change. Occurrence of flash flood and rising temperature will cause severe damage to our cropland since our agricultural land is located on slopes eventually affecting country’s food security.
