The diagrams depicts the linear process of generating electricty from wave-energy machine and the two different options for installing machines depending upon cost and output.

Overall, it is clearly noticeable that energy is generated when the air comes in either from by wave direction or air from the top. There are several tools used in the machine in order to generate electricity such as chambers, turbine and electricity generator.

In the initial stage, the wave comes inside the chamber and increases the water level inside it. Then, escalate in water level flows air into the turbine which makes the lower turbine move and circulate. As a result, it generate electricity and the air moves out from the top of the chamber. In addition to this, an energy is also generated using upper turbine. Firstly, air flows inside the chamber from the top, and then pressures the turbine to turn around which produces electricity. At last, the air moves out from the bottom of the chamber. These are two ways by which electricity is generated using wave-energy machine.

Furthermore, there are two options for installing wave-energy machine. The first option is installing at the place where there are large waves, which in turn returns high output, but cost of installation is high. The second option is used when low output is required and the installation costs for the same will be minimal as compared to other option.

Nowadays, e-commerce is the preferred way of shopping in all over the world as it has many advantages such as scalibility of customers to sellers, flexibilty to buy at any time from anywhere, better discounts etcetera; however, there are some demerits too which cannot be undermined such as increasing frauds of credit card, loss to conventional way of doing business and many more. In this essay, I will discuss both positive and negative aspects of the trend and reasons why advantages are more.

The definite advantage of buying products on Internet to customer is that they can purchase from any corner of the world regardless of time due to the fact that shopping platforms are available 24*7. An added advantage is customers gets better deals and discounts as compared to buying from retail shop and it is profitable too for the sellers as they get more number of customers. In addition to this, in the conventional way of shopping, people used to struggle in order to find relevant and satisfactory product because they had to visit various shops, in contrast to online shopping, where they can directly search and find variety of products from several sellers. The Times reported that Amazon has changed the market completely and over 60% of people across the worlds transferred from offline shopping to online shopping.

On the other hand, it has a severe demerit that it escalates the credit card fraud, considering more and more people add their card details into shopping websites. A distinct bane of this is to e-commerce seller because of high product return rate. The main reason behind that is there are some products related to size such as shirts, jeans, shoes etcetera and another reason is change in colour because of screen differences and cameras. For instance, Myntra an e-commerce platform in Inadia recently stated that arount 20% of total products sold by the sellers are returned by the buyers.

In conclusion, there are lot of perks of buying things online which are way more than its demerits; however, disadvantages can be overcomed by adding more security into the system and providing more accurate information about the product to the customer.
