The combustion of biomass can replace fossil fuels in conventional power plants

In conventional power plants a source of heat is used heat liquid water to high-pressure steam and the steam is used to turn turbines with a dynamo effect that produces electricity. This source  of energy can be anything that produces energy when decomposed.

Explanation:

Usually, this source of energy is fossil fuels because it is cheaper and has high calorific value. Biomass - carbon based organic matter such as dead tree logs-  when burned, can produce heat energy required to turn water to steam, too. Biomass is a renewable source of energy in comparison to fossil fuels.

Hydroelectric energy emanates from the potential and kinetic energy of water, usually naturally flowing water,  to turn turbines that produce electricity.

The sun is a renewable resources, unlike fossil fuels, because it is impossible to exhaust the sun's potential in all of the humanity’s existence on earth.

Choose any one of the consumer services companies and write an essay of about 500 words on how a diverse economy such as the Uni
zaharov [31]

Answer:

let's take the example of Walmart, which has the large presence in the United States and is an important part of the Consumer Services Industry.

Explanation:

Walmart began with just one store but has grown all over the country to many unique aspects of the American economy and demographics. The United States, in contrast to what many people assume, is a very diverse country.

The culture of New England is very different from that of the Bible belt. Similarly, the African American culture of Georgia is different from the casual California where there is a vast Hispanic population.

Walmart saw an opportunity in this diversity and has grown by catering to needs of all these consumers. Communities with highly dense Hispanic population stocked food items that were very different than can be found in Jewish neighbourhoods and vice verse.

This enabled Walmart to connect with each community and grow with them over the generations.

In all this, Walmart prides itself in providing benefits to US army veterans and provides jobs to women from low-income backgrounds and the disabled.

In all this, Walmart does face a number of different challenges, including:

A slowing economy can hit the profits of the company

Competition from other companies such as Costco and even international players like Aldi and Lidl can decrease their market share

Online rivals such as Amazon have long been identified as a threat to the company and is one of the biggest challenges facing the consumer service industry.

Companies like Amazon are not only involved in retail but also in selling movies, music, etc that can completely challenge the consumer service sector
