"The vendor was very nice. Prepared. We investigated the issue together and identified next steps. No issue was found and he let me know ahead of time that if he cut the drywall, he would not be replacing it. But, he did clean up after himself, which I appreciate."

I am a Ph.D level graduate in Physics as my major and Computer Science and Mathematics Minors providing 1-on-1 and 1-to-Many tutoring and test preparation services online, in your home, local library, or coffee shop from Pre-k( I teach my 4 year old) all the way to Graduate level in STEM related courses. What differentiates me from the rest is that first of all, I love teaching, second, I have the experience (I have thought all my life from High school to Graduate school as a student and Teaching Assistant), thirdly, I take pleasure is seeing someone grow in general knowledge and in particular their STEM related abilities.Finally I am very patient and value empathy. I believe my true purpose in life is to teach, although I keep trying to do other things else. In my opinion, if you are not growing and self-developing in knowledge in anything you are doing, please STOP and do something else. So it is with my tutoring. I will stop teaching and refund your full money if I feel you are not making any progress of aren't comfortable. Like I said, I take pleasure in tutoring and your progress, not you money!. I want to be happy doing what I do!! FYI I could be somewhere else teaching as a Professor in the University. For now, I am alone, as I do this part time but I would convince my spouse to join me as she also loves teaching( she is a Graduate in Mathematics and Statistics). I will also recruit more people I believe can do the job with passion and excellence. This is how I work, parents, grandparents, guardian or student call or email and after discussion using facetime, skype or google hangout to understand the student's situation, I accept or refuse the tutoring. If you like my services after the discussion, we go ahead, I accept your payment, and we make a schedule for either online or physical tutoring. If you aren't comfortable with the process after a week, I refund your money in full. I tutor students preparing for major exams like SAT, etc.

Energy Efficiency Auditing questions, answered by experts

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.
