Further, it does not expand or sag during due to high temperatures neither does it brittle due to low temperatures. The fiberglass conduit is, however, not easy to bend in the field and requires cutting and using the appropriate fittings to change directions. In addition, it cannot be used to support the luminaires. Electrical nonmetallic tubing (ENT) This is a pliable, corrugated thin-walled conduit that is flame retardant and suitable for both dry and moist conditions. The conduit is often flexible, making it easy to bend by hand.
Wind power is a clean source of energy as it produces no waste because no chemical reaction takes place. Wind power farming is highly compatible with agriculture, as it requires less than 5% of total land usage. The land can also be used to keep livestock, and crops can be planted right up to the turbine infrastructure, meaning that food and energy can be produced on the same hectare of land. Potential Challenges Wind is a fluctuating source of energy and the output over time is difficult to predict. To meet the base load energy demand, a form of energy storage needs to be utilized or it must be offset with other forms of energy.
Some juicers will breed seeds and in time, drugs within the seed can cause health problems. This is not possible by boiling. Of course, it is your decision. The judges will give you a green juice. However, you will not get too many nutrients of berries as you will boil.
Also preserving ecosystems is an advantage of shade grown coffee. This is because not cutting down as many trees which make homes for birds. This reduces carbon emissions because fewer trees are getting cut down which means that more carbon is getting absorbed by the trees that are still up. Another advantage of shade grown coffee is soil conservation. This is because conventional coffee plantations are dependent on chemicals suffer from soil decreasing and regular coffee plantations suffer from increased erosion also rainforest are removed to make sure there is fresh growing ground for the coffee.
Pure iron rarely exists outside a laboratory. Iron is produced by reducing iron ore to pig iron through the use of a blast furnace. From pig iron many other types of iron and steel are produced by addition or deletion of carbon and alloys. It is a bright white metal that is malleable, ductile and is relatively soft metal. It also has a very high tensile strength and is a moderately good conductor to heat and electricity.
However there are few applications that used plant based bio-degradable lubricants which are superior in terms of bio-degradability, especially when compared to mineral oils. Chemical modification of plant oil is an attractive way to overcome this limitation. Chemical modifications mainly
Moreover biodegradable bags require oxygen and sunlight to degrade,therefore unable to biodegrade as it would be buried in landfill. In conclusion,plastic levy might not be most effective in eliminating negative externality of consumption as although it reduces government expense and most money raised are used for environmental causes, many problems had arose from using biodegradable bags. Therefore negative advertisement about plastic bag or educational campaign that promotes advantage of environmentally-friendly alternatives such as BOC’N ROLL reusable food wrap would perhaps be a more desirable measure to reduce negative externality of plastic bag
it does not contribute to pollution and keeps our world clean. Solar energy is a very practical form of energy for lighting and heating. Solar power can be easily used to heat water tanks, pools, and spas. Its uses are endless. Disadvantage : Just like wind power, solar power also has the disadvantage of inconsistency.
In some countries no industrial composters are available and also the cost the composter is not affordable in some cases for poor countries. Proper equipment is required for the disposal and the bio-plastics should be mixed with the non-degradable plastics that can cause contamination. This can be counted as a disadvantage of bio-plastics .However, if it is the true solution producing bio-plastics to quit using non-degradable plastics, composters can be supplied to the countries officials which cannot afford to buy the industrial composters to dispose of bio-plastics. According to search it is efficient to produce bio-plastics, because it cuts down the amount of waste in landfill sites by minimizing the emission of carbon in the air during the process of manufacturing bioplastics by consuming less
Furthermore, vacuum cleaners are efficient because it takes less time and human effort to use them, especially with regard to large areas and very dirty carpets (Médina-Ramón et al 2006). 1.7.4. Convenience A sweeper is very light, easy to store and dust gathering is simple to throw away; you can sweep under beds and chairs and is simple to use. A vacuum cleaner can also be light and compact, and its power is convenient because it collects dirt automatically. Electric vacuum bags normally used must be replaced and should be within reach of an electric contact, while the bulkier units are not suitable for small
