minimum efficient scale (MES)The minimum efficient scale (MES) is the output for a business in the long run where the internal economies of scale have been fully exploited. It corresponds to the lowest point on the long run average total cost curve and is also known as the output of long run productive efficiency. The MES is rarely a single output - more likely it is a range of output levels where average cost is minimized where the firm achieves constant returns to scale. The MES will vary from

15 Nonrenewable Energy A Brief History of Human Energy Use Core Case Study Everything runs on energy. Some sources of energy‚ such as oil‚ coal‚ and natural gas—also called fossil fuels—as well as uranium used to fuel nuclear power plants‚ are nonrenewable because they take millions of years to form in the earth’s crust. Other energy resources such as the sun‚ wind‚ flowing water‚ wood‚ and heat from the earth’s interior are renewable because they can be replenished by nature within

would anyone use solar energy as an alternative energy to solve the world’s pollution problem? As humans‚ everyday we burn many different types of fossil fuels to produce ourselves electricity and to power up our vehicles‚ and so we create a lot of pollution‚ making this our own fault. With our modern technology and the abundance of the sun’s energy‚ solar energy has the ability to provide the world with electricity and different types of fluid (“Solar Energy”). Solar energy is ?e energy source. It

Should the Use of Wind Energy Be Encouraged? Fossil fuels are having great impacts toward nature such as global warming and greenhouse effect. Plus‚ the depletion of it contributes to the rising price of petroleum. Therefore‚ wind power rise as it is a source of clean‚ non-polluting renewable energy (Nash‚ 2008). This type of energy generation provides us with loads of benefits environmentally and economically. On the environmental aspect‚ wind energy does not contribute to pollution as almost

This is attributed to rising energy costs and government initiatives. Some of the key government initiatives include regulations such as Commercial Buildings Initiatives (CBI) by the U.S. government aims at making all commercial buildings completely energy independent by 2025. This implies that commercial buildings should have facilities to generate onsite power.

consumers will gain when manufacturers provide more fuel-efficient cars? Today‚ we have many different kinds of cars to choose. They have different sizes‚ colors‚ prices and models. When we buy an automobile‚ we look for the best auto to satisfy our needs like going to the store. Manufacturers provide more cars to help us in our needs. When manufactures provide more fuel-efficient autos‚ consumers save money‚ gas‚ and time. A fuel-efficient car will help us saved money. I mean think about it the

Efficient Energy Harvester for Microbial Fuel Cells using DC/DC Converters Abstract— Microbial fuel cell (MFC) is an emerging technology for sustainable energy production. An MFC employs indigenous microorganisms as biocatalysts and can theoretically convert any biodegradable substrate into electricity‚ making the technology a viable solution for sustainable waste treatment or autonomous power supply. However‚ the electric energy currently generated from MFCs is not directly usable due to the low

Should cars be more efficient? Should cars be more efficient? Well this can be so and can seem not so efficient for cars. Not always can cars be efficient. I could pop the question when is efficiency desirable for the use of cars. This will be the point of view that I will tackle throughout this paper. Now in time and time to come‚ with the rise of growth‚ I think that when this happens efficient is not that of an importance. Within some years
