In the 6am in the morning, the energy consumption starts to rise. Then energy surges around noon. Around 6pm, energy demand increases again (Figure 1). The relationship between all the variables with the energy consumption of appliances in the training set. Correlation equals to 1 is total positive correlation, -1 is total negative correlation, and 0 represents no correlation. It also gives the measurement of the linear dependence between two variables, shown in scatter plot below the diagonal, histogram plot along the diagonal and the Pearson correlation above the diagonal (Figure 2). The high correlations exist between T1 and T2(0.84), T2 and T3 (0.74), T4 and T5 (0.87), T5 and T6 (0.63), T7 and T8 (0.88), and T8 with T9 (0.86). The …show more content…
Lights as the second most important predictor pick by the RF and SVM-radial model. For GBM model, the second most important predictor is the atmospheric pressure. The data from the wireless sensor network was ranked highly in the GBM model, especially with information from the living room (RH2), the kitchen (RH1), the laundry room (T3), and bathroom (RH5) in the top position. Conclusion This study presents the data-driven predictive models for the energy use of appliances. the data set include the measurements of temperature and humidity sensor from a wireless network, weather from a nearby airport station and recorded energy use of lighting fixtures. We test the relationship between the appliances energy consumption and different predictors testing by four models (linear regression, support vector machines, random forest and gradient boosting machines) to predict energy consumption. Finding the best model by computing root mean squared error (RMSE), R-squared, and the mean absolute error (MAE). GBM and RF models give best prediction on RSME and R2 compared with SVM-radial and multiple linear regression. The best model GBM explain 97% of the variance (R2) in the training set and with 57% in the testing set with all the predictors. For all the models, the time information (NSM) is ranked as the most important predictor in appliances’ consumption. The data from the wireless sensor network is ranked highly in the GBM model, especially with information
Validate that the data entered has the correct format and is within a reasonable range.
A scatter plot diagram provides a graphical observation of how two different variables are related to one another. Looking at the data collected for credit balance of customers along with the data collected for income of customers, it’s easy to recognize that there is a correlation between the two variables. The linear positive slope indicates that an increase in the credit balance correlates with an increase in income.
Discussion Prompt: Explain where you think, in your home, you use the most energy. Estimate how much energy this item/machine/process uses. (Yes, you may need to do some research.) How much more energy does this item/machine/process use versus other items/machines/processes in your home. Provide an insightful response to at least two of your peers, using at least three sentences for each response. Do you agree or disagree with which item/machine/process they chose? Do you think there is something that uses more energy in their home?
On the daily basis I use numerous energy resources from residential, commercial, transportation to industrial. First, I use residential and commercial the most. At home I have gas heating, stove and fireplace; gas pretty much runs my house. Right now in the winter month’s gas heating is the greatest energy usages in my resident. Then on top of that we have space heaters. The heaters are intended to cut back on the gas usage but I’m not seeing much of a difference. Usage of electricity is also a huge abundance in my residents. A normal routine of using electricity varies from everything like lights
In order to figure out how variables relates to each other and the connections among the variables, or one can predict the other. I will choose three quantitative variables or two quantitative variables and one categorical variable on each pairs. I will also use graphs of scatter plots; regression and correlation to understand that how one variable affect other two variables. There are six groups below:
I believe that this number increases especially during the fall and winter time due to the weather being lower and that affecting homes. As stated in Document D, heating is 31% of the electrical usage in a home. That is the highest percentage out of all the other electrical usages. For example, appliances and computers are only 9% of the electrical usage- which are things we use all the time. Have you ever had your parents’ blame you for the electricity bill being “sky high” because you leave your light on? Well light is only 11% of the electric usage, which isn’t as much as many other things that raise the electric price! If the price is too high then I consider finding ways to reduce the
Limiting the use of our utilities is not only beneficial to our budget but also to the environment as well. Here are several useful and lesser known tips in conserving energy while you are in the kitchen. While being in the kitchen, the stove is one of the main items that will use up the most energy, so it is important to be wise with your energy consumption when cooking on it. Adjust the burners when using a gas-based cooking top so that the flames just barely touch or are a tad lower than the bottom of the pans you are cooking on. Flames that curl around a pan waste more energy. However, if you are using an electric cook top, put the pan on a coil that is similar in size. Place the pan so that its bottom lies absolutely flat on the burner. This will conserve a great deal of energy. Also, when using an electric stove, set the burners on high first and then proceed to lower it to finish the cooking. For dishes that aren't pans, turn off the burner completely at the end as the element will hold the heat for several minutes. In addition to your stoves, the oven vent on an electrical range can be very useful. If you are using an oven vent on an electrical range, you will find that the vent is under one of the burners. While the oven is in use, you will be able to feel the hot air flowing through the vent. For dishes that you would like to warm, set them on that burner. This will minimize the use of a microwave and will also optimize the use of your burners. Now, for dishes that need to cook for long periods of time, particularly over an hour, there is no need to preheat your oven (unless you are cooking a turkey that needs a crisp skin). For dishes that must be cooked just under an hour, extend the cooking time for a little bit. The only preheating that is required is for dishes that have a short baking time. Although this seems like a very obvious tip --
Seasonal factors: For example the demand for domestic energy over winter is greater than over the summer.
For one thing, simple lifestyle changes can save kilowatts of electricity. One of these involves turning off the lights and electrical appliances when leaving a room. Shutting off computers can save watts – turning them off at night, and having them hibernate during the day if not in use is a good way to save energy
How is energy produced from the resource? Nuclear energy is the power produced during a nuclear reaction. It can produce in two different ways like, nuclear fission and nuclear fusion. It is from the sun and stars which releases heat and light energy to warm up the earth. How much nuclear energy do we use? It has been said that it produces 13-14% of the world’s electricity and it accounts for 6% of the world’s energy, France and japan make up 50% alone, and the U.S. has been producing 20% since 1991. What are the prospects for this resource in the future? They say that from now until 2040 that it will go up by 14% and that the generators will be updated and new fuel cycles. What are the pros and cons for each resource? Coal: Pros- its
Behavioral measures towards achieving home energy efficiency can be described as the necessary lifestyle changes that an individual should take. The first process in the behavioral approach towards energy efficiency is to identify any energy loss taking place through conducting an inspection (Tremblay, 2012). The inspection will help in identifying the problem areas for inefficient energy use or loss and prioritizing these areas based on the
Humans today are using much more electricity than we need to in our houses and this is impacting our world more then we realise. Although electricity is a huge advantage to humans it has the complete opposite effects on our environment. By using more electricity, we are using more of the earth’s resources and if we keep going down this road then we are going to run out. The solution for this mass overuse of energy is to build houses which are more energy efficient. Features like LED lightbulbs, insulating and even positioning your house in the correct position for natural airflow instead of using air conditioning are all ways we can help improve this problem.
There are many forms of energy. The types of energy that can affect the toy car are potential energy, kinetic energy, and work of friction. Potential is the energy of an object due to its position. Kinetic energy is the energy due to motion. Friction plays a part because it shows how much energy is needed for the car to move. All these energies are intertwined in the toy car.
I, Vineet Kr. Gupta, am completed M.Tech (Energy & Environmental Management) from Kurukshetra University, Haryana, India. I wish to apply for the suitable position (Environment Management Division) in your organization in the thrust area of Environment Management.
What is energy? Energy is the ability to do work, it is the “power that comes from the use of physical or chemical resources.” In your home energy can come in many forms such as heat, light, and even electricity. The problem is some of us, meaning people, in general, know little to anything about the word energy itself. When we think about energy, we think about the energy it takes to get up in the morning. Sometimes as students we do not notice how much, and when we use energy. We use energy in everyday life, and it is very important to understand that.
