Photovoltaic technology is close related with the electronic industry where we can find severe social impacts throughout the supply chain from raw material extraction to disposal. In the PV case‚ the manufacture of solar cells involves several toxic

Considering the elements of microeconomics‚ create a list of three (3) best practices that would benefit any small business or start-up. Explain your rationale. The element of microeconomics is every business endeavor is an exchange between a buyer and a seller. Understanding the factors that determine demand and supply is the first best practice that would benefit a small business startup. The demand reflects the willingness and ability of buyers to purchase goods and services at different prices

Production–possibility frontier In economics‚ a production–possibility frontier (PPF)‚ sometimes called a production–possibility curve‚ production-possibility boundary or product transformation curve‚ is a graph that compares the production rates of two commodities that use the same fixed total of the factors of production. Graphically bounding the production set‚ the PPF curve shows the maximum specified production level of one commodity that results given the production level of the other. By

Manifesting intense magnetic activity‚ sunspots host secondary phenomena such as coronal loops (prominences) and reconnection events. Most solar flares and coronal mass ejections originate in magnetically active regions around visible sunspot groupings. Similar phenomena indirectly observed on stars are commonly

Solar Panels Solar Panels‚ also known as Solar Cells‚ convert solar energy into electrical energy. When sunlight hits the solar panel it knocks electrons loose from their atoms and then they move through the built in circuit‚ thus creating a current of energy. This energy can be stored in batteries for later use or it can be used right away. Antoine César Becquerel‚ a French scientist‚ and his son‚ Alexandre-Edmond Becquerel‚ were the first to notice photovoltaic power in 1839. They discovered

Contents Introduction Solar energy has experienced an impressive technological shift. While early solar technologies consisted of small-scale photovoltaic (PV) cells‚ recent technologies are represented by solar concentrated power (CSP) and also by large-scale PV systems that feed into electricity grids. The costs of solar energy technologies have dropped substantially over the last 30 years. The rapid expansion of the solar energy market can be attributed to a number of supportive
