2. Problem Statement Due to a rough history with the local power company, San Pablo has resorted to using power from the power company without paying their bills for 8 years There is a very real fear that killings over this matter will ensue if things remain as they are San Pablo is reliant on the electricity they have been receiving over the years and need to find an alternative solution Because San Pablo hasn't had to worry about paying for their electricity, they have fallen into bad habits in respect to power usage The biggest consumption of their electricity goes into lighting and the heating of water.

3. Goals To educate the San Pablo community about the importance of being less wasteful with their energy Come up with a solution to provide San Pablo with a source of energy that can be renewable and maintained by the local community o Microhydro appears to be the most viable system considering the geography of San Pablo

4. Solutions Education More Efficient Technology Microhydro

5. Education The people of San Pablo must first educate themselves on how to use their power in a more efficient way. It is not enough that we simply list off ways that they can conserve power. We must first develop a curriculum that explains the importance of energy efficiency in terms of how it is good for them and the world as a whole. We want to emphasize Cal Poly's "Learn by Doing" methodology by utilizing Guateca

6. Efficient Technology/Usage Limit light usage o turn off when not needed (on timers) o energy efficient light bulbs/LEDs o better windows o sky lights Better stoves Better insulation More efficient showers Cut back during peak usage/distribute the usage more evenly

8. Power Meter Assignment Students will be given power meters to measure their household power consumption for a week and ultimately the cost of their usage, along with a load curve to determine peak hour usage. The students will then be assigned to measure their power consumption the next week with the goal of achieving the lowest power consumption using what they have learned so far in their curriculum.

9. Our Electrical Usage (kWh/Month) Brittney has an electric water heater and thermostat. She also bikes to school to offset her obscenely high energy use

11. Micro-hydro Project

12. Estimated Cost of Microhydro -Assumptions- Wet Season Flow Rate: 200 L /sec Dry Season Flow Rate: 80 L /sec Elevation Change: 150 m System Efficiency of 50% 58.8 kw Production Estimated Micro Hydro System Costs Development Costs = $3,500/kw Transmission Costs = $30,000 Total System Cost = $3,500(58.8 kw)+$30,000=$235,800 Payment Down Payment = $100 per family Interest Rate = 5% Expected Annual Maintenance Costs = $10,000 Monthly Payment: $1,099.87 Monthly Payment Per Family: $8.09

13. Micro-hydro Assignment 1) Calculate the amount of power an appropriate microhydro system would generate taking into account flow rates of local rivers and the change in elevation from intake to the turbine a )Determine the lower-limit and upper-limit of the amount of power produced taking into account the difference in seasonal flow rates 2) Calculate how much power each household can utilize in the respective seasons in Watts using the proposed microhydro system 3) Calculate the amount of kWh an average household can utilize in a week 4) Compare this result to the data collected from the Power Meter Assignment 5) If the collected data from the Power Meter Assignment is significantly higher than the results from step 3, discuss ways in which a household can lower their power consumption to meet this value. 6) Using the discussed methods, try to reduce your household’s power consumption by 10 kWh

14. Environmental Importance Assignment The Majority of the worlds electricity comes from non- renewable sources These sources, particularly coal and petroleum, release tons of ozone damaging gasses Image Source: http://www.worldcoal.org/coal/uses-of-coal/coal-electricity/http://www.worldcoal.org/coal/uses-of-coal/coal-electricity/

15. Environmental Importance Assignment Similar to the carbon footprint assignment our class has done, we want students to calculate their carbon footprint as is Students can then recalculate what they predict their footprint will be if their electricity is completely provided by micro-hydro How would this affect CO 2 emissions if all of Guatemala used sustainable electricity, or all of the world?

16. Financial Importance Assignment Goals: Teach students the cost saving importance of switching to a self-sustaining electricity source Show how to do basic comparison analysis Learn basics of project investment

17. Grant Proposal The curriculum would require funding to pay for the teachers and for any teaching aids such as the power meters. The microhydro system would require funding to install and maintain the system.
