What is energy efficiency? Explain why we can think of energy efficiency as an energy resource. What percentage of the energy us

ed in the United States is unnecessarily wasted? List four widely used energy-wasting technolo- gies. What are the major advantages of reducing energy waste? List three reasons why this source of energy has been neglected.

Answer:

Energy efficiency is a determination of the amount of work one can obtain from each energy unit used. Improving energy efficiency signifies the usage of less energy to offer a similar amount of work in the forms of heat, light, transportation, and other benefits. This constitutes a largely untapped source of energy, which is clean, abundant, easily available, and cheap.  

About 84 percent of all the commercial energy utilized in the United States does not generate useful work. Approximately 41 percent of this energy generally ends up as low-quality waste heat in the environment due to deprivation of energy eminence levied by the 2nd law of thermodynamics. The remaining 43 percent is wasted needlessly, majorly because of the inefficacy of industrial motors, light bulbs, power plants, and motor vehicles.  

The four broadly used devices that waste energy are incandescent light bulb, a motor vehicle with an internal combustion engine, a coal-fired power plant, and a nuclear power plant. The prime advantages of reducing energy wastes are:

1. Reduces oil imports and betters energy security.  

2. Prolongs supplies of fossil fuels.  

3. Reduced pollution and environment degradation.  

4. Very high energy yield and low cost.  

The three prime reasons that energy efficiency has been neglected are:  

1. Energy stays artificially cheap (subsidies for fossil fuel and mining companies).  

2. Few large and long-enduring incentives for energy efficiency.  

3. Prices do not comprise cost of health and environmental influences.

A paragraph on how selective breeding is better than cloning plz 100 POINTS
harkovskaia [24]

Answer:

Selective breeding is used to promote the benefits of both animal and plant breeding inheritance. It is essentially done by controlled breeding. However, it has its own set of disadvantages, like any other agricultural method-although it is supposed to offer benefits to society. If you want to selectively breed your crops and cattle, weigh them down and decide whether that’s a good way for you.

No company patent is required.Anyone working in farming can start breeding selectively whenever they want. It is a way for him to create more profits every year, as he can grow animals and plants with different characteristics such that they can be generated over centuries, which is good for businesses. And since he is free, he only needs to be knowledgeable and well equipped in the process to achieve the best result.

It makes higher profit possible.Selective breeding encourages more beneficial plant and animal characteristics for farmers. If they have selectively bred cows, for example, these animals can produce more milk than the typical cows and the gene can be transferred to their descendants. If the method is used on crops, more than the typical ones will also be grown. Promoting these advantages will certainly increase their product’s market value. Selective breeding is certainly an perfect choice for farmers who are in a major company.

What type of attractions between water molecules occur because of water's diplor nature
leva [86]

Answer:

Explanation:

The barnacles are only able to attach themselves to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.

3.Whenever the surfaces in contact tend to move or move with respect to each other, the force of friction comes into playRequire
fredd [130]

Answer:

The correct answer is - Friction occurs irrespective of the state of the matter.

Explanation:

Friction is the force that takes place when there are two different surfaces slide or moves across one another and causes a resistance between surfaces. The friction always takes place opposite direction to the other surface direction of moving.

Pushing a book on a table, pulling a heavy cart on road all are examples of friction. The friction that occurs in liquids and gases is called fluid friction. Thus, the friction takes place irrespective of the state of the matter.
