 why do we need to use alternative energy resources

why do we need to use alternative energy resources

There is a current global need for clean and renewable energy sources. Fossil fuels are non-renewable and require finite resources, which are dwindling because of high cost and environmentally damaging retrieval techniques. So, the need for cheap and obtainable resources is greatly needed. An efficient and more feasible alternative option is solar energy. Solar energy is a more practical type of energy due to its plentiful availability; it is derived directly from the sun. In 2010, renewable energy only provided 8 percent of the total energy consumption in the United States. Many people probably wonder: if renewable energy is so beneficial, why don t we consume more of it? The answer to the question is that many of the renewable energy sources are more expensive and more difficult to

 why do vestigial structures persist in modern organisms

why do vestigial structures persist in modern organisms

It takes some time for a structure to completely lose its function, and then considerable amount of time after than for it to disappear completely. For example, the appendix is a vestigial structure. It still has some *traces* of its ancestral function. In herbivores, the cecum is the breeding ground for bacteria used for digesting cellulose. In purely carnivorous animals the cecum is reduced. In the omnivorous primates (humans, apes, and Old World monkeys of Asia and Africa), the cecum is mostly replaced with the appendix, which still has traces of its ancestral function, in that it may have some function in harboring good bacteria used in digestion, during disease. ...

 why do you choose civil engineering course

why do you choose civil engineering course

When I was about 6 to 7 years old, Iвd always get in trouble with my grandmother for digging tunnels and little dams around her yard. Iвd miss most of my meals while constructing mini cities complete with roads, buildings and rivers. As one may say, passion breeds when we are young, in my case, my path to Civil Engineering had been laid before me at that moment. Throughout my primary and secondary education I carried out thorough research about my burning passion in construction. With great mentorship from my teachers atShinimeShiimvula Primary School (Ondangwa, Namibia) andOtjikoto SSS, (Tsumeb, Namibia), I chose to major in science subjects(Physical Science and Mathematics) to pave the way to admission to pursue studies in Engineering at tertiary level. I would read about all major

 why do we have a day and night

why do we have a day and night

The Earth takes 24 hours to make one complete turn. Why do we have day and night? We have day and night because the Earth rotates. It spins on its axis, which is an imaginary line passing through the North and South Poles. The Earth spins slowly all the time, but we don't feel any movement because it turns smoothly and at the same speed. How long does it take the Earth to turn around? The Earth takes a whole day (24 hours) to makea complete turn. Why is the Sun in the sky at some times and not at other times? At any time half of the Earth faces the sun. ...

 why do we need energy in our body

why do we need energy in our body

External functions supported by energy include exercise, work and play. If you are active and have a high lean body mass to fat ratio, your energy needs are greater than someone who leads a sedentary lifestyle or has a high body fat composition, according to Sheri Barke, MPH, RD, College of Canyons Student Health and Wellness Center. Fighting invading organisms that cause infection and disease uses massive amounts of physical energy. Fever drains energy stores to restore and maintain normal temperature balance. Resting metabolic rates increased by 8 percent in 25 study participants infected with respiratory tract infections, according to a report published in the July/August 2010 issue of the БAmerican Journal of Human Biology. Б Study results indicate even modest physiological responses

why do we use a design process

What is a Design Process? Before I explain why having a design process is important, you might be wondering what a design process even is. Itвs a systematic series of steps that helps you to define, plan and produce a product youвre building в in our case, an app. It allows you to be efficient, transparent and focused on creating the best product possible.

 why do we use alternating current for mains electricity

why do we use alternating current for mains electricity

Mains electricity is the term used to refer to the electricity supply from power stations to households. Mains electricity is supplied as alternating current (a. c. ) Alternating current a. c. is one which is constantly changing i. e. the current flows in one direction and then in the opposite direction, again and again (continuously). In the UK, a. c. supply goes in one direction and then in the opposite direction 50 times in one second. Therefore, the frequency of a. c. supply is 50 cycles per second or 50 hertz. UK mains voltage is 230 Volts. Why a. c.? Alternating current can easily be converted to higher and lower voltages by a transformer. ...
