What is solar thermal electric generation? Briefly describe how it works. Disadvantages of using solar energy



Answer: The system works by collecting heat from solar energy and delivering this energy in the form of steam to turbines that produce electric power.

How it works :


An experimental 10-MW power tower near Barstow, California, is surrounded by mirror modules with reflective areas. The mirrors adjust continually to reflect as much sunlight into the tower as possible. This system was also capable of storing the energy in a molten salt heat-storage system

Disadvantages of using solar energy: 


  • It is relatively dispersed, arriving at Earth's surface like a fine mist, so that a large land area is required to generate a large amount of energy.
  • Highly centralized and high-technology solar energy units, such as solar power towers, have a greater impact on the land because they need more space.
  • Concern in the involvement of the large variety of metals, glass, plastics, and fluids used in the manufacture and use of solar equipment -> accidental release of toxic materials and other environmental problems.

Why do firms need to invest in net working capital?

Why do firms need to invest in net working capital? Answer: - Short-term financial planning is concerned with the management of the firm's short-term, or current, assets and liabilities. The most important current assets are cash, marketable securities, inventory, and trade receivables. The most important current liabilities are bank loans and trade payables. - The difference between current assets and current liabilities is called NET WORKING CAPITAL (NWC). NWC arises from lags between the time the firm obtains the raw materials for its product and the time it finally collects its bills from customers. The OPERATING CYCLE is the length of time from the purchase of raw materials to the collection of cash from customers. - The cash CONVERSION CYCLE is the length of time between the firm's payment for materials and the date that it gets paid by its customers. THE CASH CONVERSION CYCLE is partly within management's control. For example, it can choose to have a higher ...
