- Everyday we hear more bad news about our planet.
- Reports tell us that wildlife and forests are disappearing at an alarming rate.
- Newscasts give the latest word on how quickly earth is losing its protective shield (Ozone) and warming up.
- Newspapers lament the pollution of our air, water, and soil.
- What can we do in the face of such widespread gloom?
- In fact, we do not have to feel helpless. We can each learn practical ways to better our environment.
- In this project, Focus is on two major topics of Today's World, namely:
- solar energy and
- Energy Conservation
- We hear everyday, on TV, newspapers, magazines, that we have to save the planet.
- Did you know there's areas in this world who don't have Power, they don't even know it exist, but on the other part of the world we as humans are wasting it.
- There is an alternative to this problem, and a good one.
- We have it on the top of our head everyday.
It Is called. 7. SolarEnergy (A very brief introduction andits advantages) 1 8.
- Solar Energy, the energy generated by the sun. This energy is in the form of electromagnetic radiation and travels to the earth in waves of various lengths.
- Some of the radiation becomes evident as heat, some as visible light.
- All life on earth depends ultimately on the sun's radiation.
- It warms the earth and provides the energy that green plants use to make their food. (Without plants, there would be no animals, since all animals must feed on plants or on plant-eating organisms.)
- Since ancient times attempts have been madewith varying successto put the energy from the sun to practical use.
- In the third century B.C., the Greek mathematician and physicist Archimedes is said to have used the sun's rays reflected from mirrors to set fire to an invading Roman fleet.
- In the 19th century, John Ericsson, designer of the ironclad warship Monitor, built an engine that was powered by the sun's energy.
- You've probably seen calculators with solar cells -- devices that never need batteries and in some cases, don't even have an off button.
- As long as there's enough light , they seem to work forever.
- Although larger panels aren't as common as solar-powered calculators, they're out there and not that hard to spot if you know where to look.
- In fact, photovoltaics -- which were once used almost exclusively in space, powering satellites' electrical systems as far back as 1958 -- are being used more and more in less exotic ways.
- The technology continues to pop up in new devices all the time, from sunglasses to electric vehicle charging stations.
- The hope for a "solar revolution" has been floating around for decades -- the idea that one day we'll all use free electricity fro m the sun .
- This is a seductive promise, because on a bright, sunny day, the sun's rays give off approximately 1,000 watts of energy per square meter of the planet's surface.
- If we could collect all of that energy, we could easily power our homes and offices for free.
12. Did you know?
- More than 10,000 homes in the United States are powered entirely by solar energy.
- Enough sunlight falls on the earth's surface every hour to meet world energy demand for an entire year.
- Silicon from just one ton of sand, used in photovoltaic cells, could produce as much electricity as burning 500,000 tons of coal.
13. Advantagesof SolarEnergy 14.
- Solar energy is everywhere, its abundant and well practically never run out.
- Even in mid winter we are blessed with a moderate amount of natural daylight provided courtesy of the sun.
- Okay, it might not be sunny everyday but we are still experiencing radiation from the sun and it is this which can be gleaned for our own renewable energy purposes.
- Thus the need for finding a long lasting energy resource is over!
Solar Energy Is Abundant 15.
- Solar energy is completely free.
- Sure, there is an initial capital cost but once you have made the investment the energy harvested from the sun costs you nothing.
- No one will be sending you a bill for sunshine.
- Thus no worries of spending enormous amounts of your salary in satisfying your energy requirements.
Solar Energy Is Free 16.
- While solar photovoltaic are still relatively expensive, the technology is growing rapidly as is production and as a result the costs involved are coming down and is now cost effective.
- Solar hot water panels have been greatly improved in recent years and, with lower cost, payback times for domestic systems can no be as short as five years.
- As coal, gas and oil prices continue to rise solar energy will become a viable alternative.
- Its secure. We live in uncertain times and we are increasingly relying on our fossil fuel supplies coming from areas abroad over which we have little or no control.
Solar Energy Is CostEffective 17.
- Finally solar energy is clean.
- It is a clean alternative to fossil fuels and nuclear power and it will never run out. Its silent.
- Solar power can be captured anywhere without creating noise pollution that might otherwise up set neighbors and wildlife.
- It works wherever the sun shines. It doesnt matter how remote, solar can generate energy where no other form of power can be obtained.
- Thus, no danger of damaging our already damaged environment further and you can be part of the Green initiative, lower your carbon footprint, and save our planet from harmful greenhouse gases.
Solar Energy Is Clean 18. So, for a brighter future LET THE SUNSHINE IN !! 19. Energyconservation 2 20.
- We all know that its important to save energy.
- In fact its been impossible to ignore the headlines telling us to do our bit for the environment, reduce our carbon footprint, adopt a greener lifestyle, and so on.
- But how many of us know the hard facts as to why we need to change our ways, and why saving energy is so important?
- We need to motivate ourselves into becoming more efficient with the way we use energy in the home, at work and in our everyday lives.
21. Its simple Definition
- Energy conservation refers to efforts made to reduce energy consumption.
- Energy conservation can be achieved through increasedefficient energy use, in conjunction with decreasedenergy consumptionand/or reduced consumption from conventional energy sources.
- Energy conservation can result in increasedfinancial capital,environmentalquality,national security, personal security, andhuman comfort.
- Individuals and organizations that are directconsumersof energy choose to conserve energy to reduce energy costs and promoteeconomic security.
- Industrial and commercial users can increase energy use efficiency to maximizeprofit.
22. Energy Conservation inIndia 23.
- Petroleum Conservation Research Association (PCRA)is an Indian government body created in 1976 and engaged in promoting energy efficiency and conservation in every walk of life.
- In the recent past PCRA has done mass media campaigns in television, radio & print media.
- An impact assessment survey by a third party revealed that due to these mega campaigns by PCRA, overall awareness level have gone up leading to saving of fossil fuels worth crores of rupees besides reducing pollution.
- Bureau of Energy Efficiencyis an Indian governmental organization created in 2002 responsible for promoting energy efficiency and conservation.
24. Major AdvantagesofEnergy conservation 25.
- Less need to secure oil and natural gas overseas with attendant military and civilian casualties while costing hundreds of billions of dollars
- Fewer power plants and liquid natural gas ports are needed
- Less air pollution
- Less drilling for oil in Alaska and near national parks
- Less global warming and attendant environmental destruction
- Energy conservation has saved the need for many power plants and fuel imports.
- It has also avoided CO2and environmental pollution.
- Solar energy is a reliable and never ending source of energy. Although the initial cost of using the solar energy may be high, the high price can be recovered as after the system is installed, there will be no cost of producing the electricity.
- We start living in an atmosphere, where we would not be selfish, looking at our needs but also pondering over the needs of our future generations.
