TOPIC #1 SOLAR POWER
TOPIC #2 MISSION TO MARS
We need to learn how to begin body paragraphs. The topic sentence sets the organization of the paragraph and keeps the paper on topic. How does it differ from the thesis? We will investigate. The thesis comes at the end of the introductory paragraph.
Follow the example below. Thesis: Rome fell because of pressure from the barbarians, a stagnant economy and a lack of political leadership.
(Body Paragraph 1 begins with) TS1: One reason Rome fell was the pressure from the northern tribes of the Verangeans.
(Body Paragraph 2 begins with) TS2: Another cause of Rome's demise was the economy.
(Body Paragraph 3 begins with) TS3: Perhaps the largest problem that led to Rome's downfall was the political leadership or lack thereof at the time.
Write thesis statements for each topic then write topic sentences (first sentences) for each body paragraph. Hint there are five paragraphs, how many topic sentences in a five paragraph essay? Each topic sentence should identify one cause (reason) for the problem or event.
Sometimes you'll want to narrow the topic for a good cause paper. Three reasons for global warming is a good environmental cause paper because it takes a huge idea (the environment) and makes it more manageable for a five-paragraph paper.
Explanation / Answer
TOPIC 1# SOLAR POWER:
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination.
Thesis statement: Development and deployment of solar energy.
Topic sentence 1 (TS1): Development of solar technologies involves history of development of solar technologies.
Early development of use of solar power started in 1860s because of the expectation that coal would soon become scarce. World’s first solar plant installed in New York in 1884. However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum. In 1974 it was estimated that only six private homes in all of North America were entirely heated or cooled by functional solar power systems. The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies. In current scenario solar power is widely used in many countries. Worldwide growth of photovoltaics has averaged 40% per year from 2000 to 2013 and total installed capacity reached 303 GW at the end of 2016 with China having the most cumulative installations (78 GW) and Honduras having the highest theoretical percentage of annual electricity usage which could be generated by solar PV (12.5%). The largest manufacturers are located in China.
Topic sentence 2 (TS2): Different solar technologies are being used to convert solar energy into electricity and its deployment.
Many industrialized nations have installed significant solar power capacity into their grids to supplement or provide an alternative to conventional energy sources while an increasing number of less developed nations have turned to solar to reduce dependence on expensive imported fuels (see solar power by country). Long distance transmission allows remote renewable energy resources to displace fossil fuel consumption. Solar power plants use one of two technologies:
· Photovoltaic (PV) systems use solar panels, either on rooftops or in ground-mounted solar farms, converting sunlight directly into electric power.
· Concentrated solar power (CSP, also known as "concentrated solar thermal") plants use solar thermal energy to make steam, that is thereafter converted into electricity by a turbine.
Topic sentence 3 (TS3): Cost of whole process from converting solar energy into electricity till its deployment.
Adjusting for inflation, it cost $96 per watt for a solar module in the mid-1970s. Process improvements and a very large boost in production have brought that figure down to 68 cents per watt in February 2016, according to data from Bloomberg New Energy Finance. Palo AltoCalifornia signed a wholesale purchase agreement in 2016 that secured solar power for 3.7 cents per kilowatt-hour. And in sunny Dubailarge-scale solar generated electricity sold in 2016 for just 2.99 cents per kilowatt-hour -- "competitive with any form of fossil-based electricity — and cheaper than most. In its 2014 edition of the Technology Roadmap: Solar Photovoltaic Energy report, the International Energy Agency (IEA) published prices for residential, commercial and utility-scale PV systems for eight major markets as of 2013 (see table below). However, DOE's SunShot Initiative has reported much lower U.S. installation prices. In 2014, prices continued to decline. The SunShot Initiative modeled U.S. system prices to be in the range of $1.80 to $3.29 per watt. Other sources identify similar price ranges of $1.70 to $3.50 for the different market segments in the U.S., and in the highly penetrated German market, prices for residential and small commercial rooftop systems of up to 100 kW declined to $1.36 per watt (€1.24/W) by the end of 2014. In 2015, Deutsche Bank estimated costs for small residential rooftop systems in the U.S. around $2.90 per watt. Costs for utility-scale systems in China and India were estimated as low as $1.00 per watt.
TOPIC #2 MISSION TO MARS
Thesis statement: Mission to Mars: challenges and future in Mars.
Topic sentence 1 (TS1): Objective of NASA scientists to make human life possible on Mars and study challenges over there.
Topic sentence 2 (TS2): NASA's Human Research Program (HRP) has been trying to understand the effects of radiation on the human body and how to reduce it.
Topic sentence 3 (TS3): Major concern of sending humans to Mars is the effect of space radiation on the astronauts of such a mission.
Topic sentence 4 (TS4): One of our biggest challenges on a mission to Mars is protecting astronauts from radiation.
Topic sentence 5 (TS5): The effect of the Galactic Cosmic Rays (GCR) on the human body has to be studied in depth to effectively counter it. GCRs that come from exploding stars known as supernovae outside the solar system are the most harmful to the human body.
