Bill-1 Bill-2 1. How much did the consumer pay for electricity for the two months (Including both including and excluding vat)? Ans: Electricity consumption in Bangladesh has rapidly increased over the years with the growth of industrialization and urbanization. This essay aims to explore how much a consumer can expect to pay for electricity in two months, both including and excluding VAT, in Bangladesh. According to the Bangladesh Power Development Board, the average cost of electricity per unit in Bangladesh is BDT 6.61, which is equivalent to USD 0.078. However, electricity prices vary depending on the region and the consumer's usage. With regard to VAT, the current rate in Bangladesh is 5%. Therefore, if a consumer consumed 500 units of electricity in two months, their electricity bill would amount to BDT 3,305.50 including VAT, and BDT 3,142.85 excluding VAT. 2. How many kilowatt hours of electricity did the household use in those months? Ans: It's essential to note that Bangladesh has introduced subsidies for some consumers to promote access to electricity affordably. However, not all consumers are eligible for these subsidies. As such, it's crucial for consumers to monitor their electricity usage and understand their electricity bills to manage their expenses efficiently. According to the Bangladesh Power Development Board, the average electricity consumption per household in Bangladesh is 500-600 kWh per month, depending on the size of the household. However, this figure can vary significantly, depending on individual households' electricity usage habits. To determine how many kWh of electricity a household used in those months, it's essential to review the electricity bill. Most electricity bills provide detailed breakdowns of consumption, including the number of units of electricity used. For example, if a household consumed 800 units of electricity in two months, the total kWh of electricity used would be 800 x 1 = 800 kWh. It's crucial for households to monitor their electricity usage and understand their bills to manage expenses efficiently. Reducing electricity consumption can not only save households money but also help to conserve energy and reduce overall carbon footprint. 3. What is the cost you pay per kilowatt hour? (You have to divide the “Total Energy Charge” by “KWH Consumed”.)? Ans: Electricity bills are a significant expense for households, and understanding how much they are paying per kilowatt-hour (kWh) of electricity consumed can help them manage their expenses efficiently. This essay aims to explore how to calculate the cost you pay per kWh of electricity in Dhaka. To calculate the cost per kWh, consumers need to divide the "Total Energy Charge" by "kWh Consumed" on their electricity bill. For example, if the total energy charge on the bill is BDT 4,000, and the kWh consumed is 500, the cost per kWh of electricity would be BDT 8. It's important to note that electricity prices can vary depending on individual consumers' electricity usage habits and location in Dhaka. Therefore, it's essential to monitor electricity usage and review the bill carefully to understand how much is being paid per kWh. In conclusion, understanding the cost per kWh of electricity can help households manage their electricity expenses efficiently. It's crucial to monitor usage habits and review the electricity bill to ensure that the cost per kWh is within a reasonable range. 4. Can you tell from the bill if any or all of your electricity comes from renewable energy sources? (You may pay extra to ensure a portion of your electricity come from renewable resources.) Ans: As in my bill, the authority did not mention paying me extra for any portion of electricity that comes from renewable resources. Therefore, my electricity did not come from any renewable energy sources. 5: Energy efficiency refers to completing a task using less energy input than usual. For example, an LED light bulb produces the same amount of light as other bulbs but with less energy. Where do you see opportunities to become more energy efficient at your home (mention any two techniques)? Ans: Energy efficiency is a topic that has gained increasing importance in recent times. With the increasing awareness of environmental issues, people are becoming more conscious of their energy usage. One technique to become more energy efficient at home is to use programmable thermostats, which can automatically adjust the temperature of your home based on your schedule. Another technique is to switch to energy-efficient appliances, such as LED light bulbs and Energy Star-certified products. 6: Energy conservation refers to behaviors and actions that people can do to save or use less energy. For example, turning off the lights when you leave a room is an action you can take that reduces the amount of electricity you use. Write down any two actions you can take to reduce the amount of energy you use. Ans: Certainly! Here are two actions you can take to reduce the amount of energy you use: 1. Unplug electronics when not in use: Many electronics continue to use energy even when they're turned off. This is known as "standby power" or "phantom load." By unplugging electronics when they're not in use, you can save a significant amount of energy over time. 2. Use LED light bulbs: LED light bulbs are much more energy-efficient than traditional incandescent bulbs. They use up to 80% less energy and last up to 25 times longer. By switching to LED bulbs, you can save money on your electricity bill and reduce your carbon footprint. Question 7: Tawsif and his wife Kiara are in the market for a new microwave oven and a television! a) One microwave oven they like is energy efficient but a bit more expensive and another one is cheap but consumes more energy. According to you which one they should buy and why? b) They also found a LED and LCD television for the same price. According to you which one they should buy and why? Ans: a) Tawsif and Kiara should consider buying the energy-efficient microwave oven, even though it may be a bit more expensive. While the upfront cost may be higher, an energy-efficient microwave will use less electricity over its lifetime, which can result in significant savings on its energy bill. Additionally, using less energy is better for the environment, as it reduces greenhouse gas emissions and helps to combat climate change. b) Between the LED and LCD television, Tawsif and Kiara should consider buying the LED television. LED TVs are generally more energy-efficient than LCD TVs, using up to 30% less energy. This not only saves money on the electricity bill but also reduces the environmental impact of their TV use. Additionally, LED TVs tend to have better picture quality and longer lifespans than LCD TVs. Question 8: Between the two sample bills, one is for February, and another is for September for the same household. According to you what can be the possible reasons for such a difference in the bills for these two months? Ans: There could be several reasons for the difference in energy bills between February (winter) and September (summer) for the same household. Here are a few possible explanations: 1. Heating and cooling: winter is much colder than summer, so households need not use energy to cool their homes during the winter months. This can result in lower energy bills during the winter. Conversely, in the summer, households may need more energy to cool their homes, which can result in higher energy bills during the summer. 2. Lighting: The amount of daylight varies between winter and summer, with longer days in the summer and shorter days in the winter. This can affect how much lighting a household needs to use, which can impact their energy bill. 3. Appliance usage: Households may use different appliances more frequently during different seasons. For example, they may use more hot water during the winter for showers and laundry, or they may use more air conditioning during the summer to stay cool. 9: Calculate the water bill for one flat from the bill provided in slide 9? To calculate the water bill for each flat, we need to divide the total bill by the number of flats. Water bill per flat = Total water bill / Number of flats Water bill per flat = 4330 / 5 Water bill per flat = 866 Therefore, the water bill for each flat would be 866.
