Transcript of The Real Solar Energy Presentation

By The E.S.C.C.C Solar Energy at Mohawk! Who we Are We are the Exploring Solutions to Climate Change Class, in Mohawk Trail Regional High School. Our Goal Our intention is to leave a positive legacy for the other students at Mohawk. Why? Our Plan Benefits •Creating our own solar energy would make our school more sustainable by reducing our carbon footprint.

•Having solar panels on our school roof would also encourage, educate, and inspire students to be more "Green" forever, in and out of school.

•Over time, creating our own solar energy, would lower the cost of our energy bill.

•A solar array could be mounted on the roof with minimal penetration. Challenges Because we want to help our school and our future. To accomplish this goal we need to: -Reduce Mohawk's carbon footprint. -Convert our use of non renewable energy to renewable energy. ? (This could be us!) aaasswdawefwerg7ye5th435 To propose to the Mohawk Administration a plan to put up solar panels on the new school roof, use the solar panels' energy to power some of the school, and reduce our carbon footprint. Mohawk's Recent Energy Use •Cost/Expense (we will expand on this later)
•Designing the Solar Array (i.e. size, space)
•Project oversight
•Technical Assistance Needed Other Schools and What they have Done Info About Solar Panels The Solar Box -Hoosac Valley High school is currently investing some of their 42 million dollar school renovation money in 570 kilowatt solar array. 25% Option -Our annual usage of electricity is around 1,118,880 kWh.
-We are charged about $0.06 per kWh, which means we spend around $67,000 per year. This system would require
22,009 sq feet of roof space
(shaded in the picture on left)
and would produce 220.10 kW The 25% option means that we would use solar panels to generate 25% of our electricity to reduce our carbon footprint. What It Is: An insulated box that when put in the Sun
the air in the box heats up.

The Materials: One cardboard box, black trash bags, clear plastic, insulation, duct tape, silicone sealant, a
wood frame and screws.

An Example of What it Does: We put the box outside
at 11:30 am while it was 45-50 degrees out and within 40 minutes the temperature in the box had
rose to 180 degrees. Overall, this entire system would cost between $500,000 and $600,000. But don't get scared, it won't really cost us that much. With help from a leasing group such as the Hampshire Council of Governments we could get the array installed with little to no cost. Conclusion! What: To get solar panels at Mohawk

Why: Because it helps stop climate change and it influences students to make a change.

How: By suggesting to the Mohawk administration why they should get solar panels at Mohawk and how to get them.

When: ASAP 50% Option The 50% option is simlar to the 25% option, but better. We would save twice as much energy and twice as much money. We would need 44,018 sq. feet to set up a solar array that would generate 440.20 kW. (right) -The average we pay per day is about $180. How Much Would We Save? Climate Change Greenhouse Gas- Greenhouse gasses are gaseous elements of the atmosphere that absprb and emit heat energy.

Carbon footprint- The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide

“Green”-“Green” is often used to describe efforts to reduce the impact of modern human life on the rest of the natural world.

(There is no single real way to define “green”) The system would cost around $1,100,000 But, just like the 25% percent option, we could receive help from a leasing group to lower or eliminate the cost of installing the panels. -A kilowatt (kW) is a unit of energy equal to 1000 watts.
-A kilowatt hour (kWh) is a unit of energy that is equal to 1000 watts over an hour of time. -Beverly High School installed an 83 kilowatt solar array in 2009 with a $300,000 grant from Massachusetts Renewable Energy Trust •The electrons in the silicon are photo-reactive (they react to sunlight)
•Instead of just wiggling in place and creating heat like most electrons, they move around and create an electrical current
•The solar panel creates a DC (Direct current) which an inverter changes into AC (Alternating current). Most electrical appliances run on AC.
•With today’s technology the standard solar panel generates 240 watts. o From the inverter the electricity goes to the electrical panel.
o Then the electricity goes to the utility meter, where the watts are metered, then sent into the electrical grid.
o Instead of just taking energy from the grid, with the system, we will also be replenishing the grid and getting paid for the energy we produce. · Solar is a renewable energy, meaning it will never run out
· We greatly depend on oil, an exhaustible resource
· Creates releases carbon into the atmosphere, carbon is a greenhouse gas
· A slight increase in temperature (4 degrees Fahrenheit) however can have a great impact on the ecosystem.
· There could be extreme weather events, some of which include heat-waves, sea levels rising and intense Atlantic hurricanes, particularly in the Northeast and Midwest.
· Hundreds of millions of people could be greatly affected in negative ways. Key Points About Climate Change GCC has contributed a considerable amount of money to making their school a “Green” school. They have laid out a 79 kilowatt solar array. They have also Installed a geothermal plant which reduced the cost of their heating and cooling costs by about 48%. In addition GCC has added a new addition to their school which relies on passive solar energy for a portion of their lighting and heating
