Click Here to Lean More About Solar Energy
Sun is our main energy source. Solar power will not end, or in another sense, we will not live to see the end of our sun. Solar energy is one of the most important sources of renewable energy. It sends us unimaginable amount of power everyday hidden in its rays.
According to research data currently available, the Sun radiates 174 Petawatts (Pw) of solar energy every day. Out of this roughly 30% of energy is reflected back to space, and another major share is absorbed by our atmosphere. Even if we get only 10% of this energy which is about 17.4 Pw per day, it is still more than the whole daily energy requirement worldwide.

Wind energy has been converted to other forms of useful energy, especially mechanical form even long time back. Energy stored in Wind is used to turn a windmill and then to used to grind grains and other stuff.
Unlike solar power, wind energy is always present, day and night alike. This is a very important advantage of using wind power. Wind power is comparatively cheap to produce. It takes little space when compared with solar panels. Today Europe, especially Germany is leading the way in Wind energy.
There are number of ways to use the power of wind. The wind mill is the common choice. Nowadays windmills are almost always used to produce electricity. If you want to learn more about wind energy visit our wind energy archive. Our free eBook renewable energy guide has a complete section on using wind energy. You may download it for free, by following this link.

Just like Wind Power, people from ancient world knew how to use the power of flowing water to do something useful.
like turning a waterwheel and grinding their grains. Hydropower today though is mainly discussed with electricity generation. There are thousands and thousands of dams built around the world to convert energy stored in water flow into electricity.
Unlike, solar or wind, hydropower is more stabilized. Most countries use hydropower in big scale to produce electricity and achieve some other benefits is create like irrigating the lands and controlling floods. Currently micro hydro plants are gaining in popularity. Small hydroelectric plants are used to power up small communities.
You need higher capital investment to build a hydropower plant though. But hydroelectric plants are very much cost effective to operate in long run. More information about hydropower can be found here on our archive. We have a dedicated section on hydropower in our free eBook the renewable energy guide. You can download this eBook 100% free by following this link.
Learn More About Geothermal Energy. Download "The Renewable Energy Guide" Free
Earth crust is heated and its molten rocks forms lava. This heat is a great energy source. Earth’s heat is available regardless of the place, and it is available 24 hours a day and 7 days a week. This makes geothermal energy a great reliable renewable energy source.
Obviously, building geothermal power plant will cost more, as it is little complex to build. But it works almost on autopilot. Only little maintenance is needed. This makes the operational costs of the plant low.
Iceland is the leader in geothermal energy. Nearly 18% of their energy comes from geothermal while US has a great potential too. You can read more about geothermal energy here. Renewable energy guide contains very informative section on geothermal energy. You can download the eBook 100% free by following this link.
Learn More About Biomass Energy. Download "The Renewable Energy Guide" Free
Biomass is the most commonly used source of renewable energy. Even the ancient man knew how to use wood to cook their food using firewood. But today, biomass energy mainly refers to burning or using materials like wood and different types of seeds to produce electricity.
Biomass has created a separate market by substituting the traditional oil with the biofuel or biodiesel. This energy sector is becoming. Ability to make your own biodiesel in your own backyard is another reason for the resent popularity behind biodiesel.
There are diverse opinions about using biomass excessively. We have discussed them on this site as well as on the renewable energy guide. You can see our biomass section for more details. You can download our free eBook renewable energy guide for even more information.
Learn More About Tidal Energy. Download "The Renewable Energy Guide" Free
Tides are a great source of renewable energy. Tides are created due to gravitational pull of earth, moon and sun. This is a complex natural behavior. Rising water levels provides a great opportunity to generate reliable renewable energy.
Unlike other sources, tidal waves can produce large amount of electricity with a high degree of reliability. This makes tidal energy a key competitor in commercial renewable energy sector. Building a tidal renewable energy plant needs large sums of capital. Also the technology is costly and relatively new.
Tidal waves are only one form of ocean energy. There are other ways we can use the vast amount of energy hidden in the oceans. These are discussed in our free eBook renewable energy guide. You may download this by following this link. You can learn more about the tidal waves by reaching our tidal energy archive.
There are more renewable energy sources emerging. But what listed above are more stable technologies.
In summary, we have many options open to go green with renewable energy. We can save lots of money if we tap into these alternative energy sources. In addition we will find solutions for the global environmental problems we are facing today.
Today, we have an option to use these alternative sources to produce energy. But tomorrow, we will not have an option; we will have to optin to renewable energy sources whether we like it or not. Ever decreasing oil and coal reserves and environmental crisis we are facing even today will leave us no other option. So act today, go green.

Using Microsoft Excel. Plagiarism, whether intentional or unintentional, is a big problem for universities. Not only is it an issue of unfair use of copyrighted material, it speaks to an ethical issue of cheating. (Please refer to the Microsoft Excel tutorials in the appendices of the Constellation text.)
Consider the following statistics. According to the plagiarism.org (2013), a survey conducted by Donald McCabe between 2002 and 2005 that included 63,700 US undergraduates and 9,250 graduate students revealed the following data:
36% of undergraduate and 24% of graduate students admit to “paraphrasing/copying few sentences from Internet source without footnoting it.”
38% of undergraduate and 25% of graduate students admit to “paraphrasing/copying few sentences from written source without footnoting it.”
14% of undergraduate students and 7% of graduate students admit to “fabricating/falsifying a bibliography.”
7% of undergraduate and 4% of graduate students self-report copying materials “almost word for word from a written source without citation.”
7% of undergraduate and 3% of graduate students self-report “turning in work done by another.”
3% of undergraduate and 2% of graduate students report “obtaining paper from term paper mill.”
In Excel, create a worksheet that addresses the following:
In cell A1, enter the following title for this worksheet: Student Plagiarism Statistics.
In cell A3, enter the following: Form of Plagiarism.
In cell B3, enter the following: Undergraduate.
In cell C3, enter the following: Graduate.
In cell D4, enter the total number of undergraduate students that participated in the study 63,700.
In cell E4, enter the total number of graduate students that participated n the study 9,250.
Beginning in cell A5, enter each of the six categories of plagiarism identified by this report, one in each row. (These categories are found under the “Academic Integrity in College and Graduate School” section showing the results of the survey done by Donald McCabe.)
Beginning in cell B5, calculate the number of students that admitted to each offense. To do this, you will need to calculate the number of students based on the percentage provided.
For example, if there were 63,700 undergraduate students that participated in the survey and 36% admitted to paraphrasing/copying a few sentences from an Internet source, then that would mean that 22,932 students admitted to the offense (63,700 * .36). Complete these calculations for all six categories. Be sure to enter formulas and use proper cell referencing, e.g. = D4*.36
Calculate the same data for graduate students beginning in cell C5.
Format all cells with the appropriate data types. Set numeric fields with no decimals.
Once you have completed the calculations, select the data cells in the table to create your chart.
Create a chart that will visually depict the data, in a way that makes it easy to see the largest areas of
plagiarism problems. A good example might be a column chart that shows undergraduate and graduate
data side by side. The choice of chart is your own.
Finalize your worksheet by making sure all columns are formatted to accommodate the size of the data.
Format your chart as needed to assure that the chart looks clean and neat. Be sure that your worksheet
looks professional and polished.
