Stay WARM with These Energy Saving Tips

Winter is here. This means, present shopping, sipping on hot cocoa, and time spent at holiday gatherings with family and friends. For those of us who love conserving energy, the winter season also means saving money by being more efficient.


Here are 10 tips below:

  1. Maximize insulation

About 25% of heat is lost through the roof. It can be substituted by installing 25 cm of insulation throughout your loft. Although it’s a costly upgrade, it can save you more long term.

  1. Time central heating

Programming your boiler to turn on 30 minutes prior to waking up in the morning – but at a lower temperature to be cost effective. Boiler heats up at a consistent speed no matter what you set the thermostat to. Don’t make the mistake of leaving your heat on low all day – then you are paying for heat you don’t need.

  1. Install Solar Panels

There are endless perks as to why you should go solar: reduce your bills, great return on investment, increase your house value, and never fear utility companies again.

  1. Use LED Holiday lights

LED lights are at minimum 75% more energy efficient and durable up to 25 times more than traditional incandescent lights. Using LED lights will you joy knowing that you won’t be spending a bundle while staying festive.

  1. Keep The Lights Off

If you plan on going away for the holidays, save money while you are away by making sure all lights are turned off. This includes lights in: garage, backyard, patio, or front porch lights.

  1. Unplug Electronics

While you’re away on vacation, unplug items in the kitchen and around the household to save money and energy. Although they are in use, they still use energy while plugged in. Electronics such as: kitchen appliances, DVDs, TVs and computers can all take a break from the wall socket.

  1. Use your curtains and take advantage of daylight savings

Heat from the sunlight is given freely, so why not make use of it. Allowing the sun to shine through the curtains during the day warms up the glass windows; projecting heat to the walls of your home. As the sun goes down, close your curtains to trap the warmth. Make sure you don’t have any hidden leaks or gaps that prevent the warm air from staying in.

  1. Keep the Kitchen Warm and Cozy

While you are cooking, boiling, and baking, all that heat accumulated will keep your kitchen warm without having the need to turn the thermostat. Try making a cup of hot cocoa, something cooking in the crock pot, and bake cookies to get your kitchen stirring up heat!

  1. Turn the dial down

This may appear counterintuitive, but stick with us. The World Health Organization has suggested to keep room temperature at a minimum of 70 degrees. A studies shows that turning down your thermostat 5 degrees. That could reduce your electricity bill by almost 10%! Keeping your dial at 65 degrees will save you money and avoid living in a cold home.

  1. Adjust Thresholds

Another step to keeping your home warmer is to prevent heat from breaking away through gaps and cracks in walls. A few apparent ones are easy to find: pipes, cables, behind the washing machine, under kitchen cupboards, key holes, and around sinks and toilets.

Water cooling solar panels can potentially save you 20% on air conditioning

New water cooling solar panel is a technology that can significantly reduce the cost of industrial air conditioning and refrigeration.

This discovery has been made over the last few years by the researchers at The University Standford. This experiment was conducted over three days, placing three water panels each 0.37 square meters and a rate of 0.2 per minute on top of the roof of the building on Stanford campus. The outcome of this experiment resulted in their step up cooled down the water close to 5 degree Celsius below the temperature over the three days of testing. Following, they used the data collected from the experiment to simulate how these panels would work cooling a two-story office building in the non other extremely hot and humid climate of Las vegas. The result of this second experiment was a 20 percent decrease in the building’s air conditioning electrical demand. Day to day, the savings ranged between 18 percent to almost 50 percent.

How it works:

A plastic layer with a silver coating reflecting almost all sunlight is placed over the water coolers on the roofs. The incoming sunlight is mirrored off so the panel stays cool in the summer sun while the second layer is a snaking tube. A snaking tube is where the water is piped through and sheds heat to the plastic. The heat is then emitted by the plastic at a wavelength in the middle of the region of the infrared spectrum. It is not absorbed by the atmosphere but instead travels in the direction of outer space. Lastly, the entire panel is wrapped in a thermal shield plastic housing that protects virtually all the heat radiated away comes from rotating water and not the surrounding air.

“This research builds on our previous work with radiative sky cooling but takes it to the next level,” says Aaswath Raman, co-lead author of the study. “It provides for the first time a high-fidelity technology demonstration of how you can use radiative sky cooling to passively cool a fluid and, in doing so, connect it with cooling systems to save electricity.”

Moving forward with developing this new device, the Stanford researchers have founded a company called SKYcool Systems, and presently working on incorporating the water cooling solar panels into air conditioning and refrigeration systems.


Solar Helps

Solar Energy Keeps Homes and City’s Traffic lights running in Florida after Hurricane

Using energy stored with solar panels, a few homeowners were able to go “off-grid”, proving how shared power can speed future storm recovery.

After Hurricane Irma hit, more than 40 percent of Florida’s residents lack electricity, and for some, may not see light for days or even weeks. Roughly 6.7 million residents in Florida including Georgia, North and South Carolina, are in risk of a power outage.

One resident named Pereira, installed rooftop solar panels and an inverter that allows him to use solar power without being connected to the grid. Fortunately he did made this wise decision a mere two weeks before Hurricane Irma hit. Pereira was able to wake up amidst the storm, use his appliances, with wifi allowing him to survive and sustain his at home IT consultant while his nearby neighbors waited for grid power to return.

Although this is an expected occurrence of a hurricane, homeowners like Pereira, some businesses, and even cities were able to leverage the sunshine state’s solar panel while the grid was down. A greater amount of rooftop solar arrays are connected to the grid, meaning that when the public power is out, the rooftop solar power is unavailable – with the exception of having a stand-alone inverter like Pereira does or a battery system like the Tesla Powerwall.

Pete Wilking, president of A1A Solar Contracting in Jacksonville, said “Events like Irma have made people aware of how dependent we are on electricity,”. During this time, local solar contractors and companies have been taking advantage of this adversity to experiment with solar technology to run their home and businesses. Wilking was benefiting from using his home rooftop solar and battery storage system throughout the duration of the storm.

Cities have also taking advantage of this by installing off-grid solar power systems to power traffic lights while the grid was down.

In the course of the worst part of the hurricane – 300,000 people lost power in Broward County. Coral Springs installed 13 lights in prime spots throughout the city.

Solar energy supporters say that now as the city of Florida rebuilds damaged power infrastructure – now couldn’t be a better time for Florida to consider grid resilience and bring on renewable energy.

Tesla Powerwall 2

Going off the grid with Tesla’s Powerwall

Back in 2015, Tesla Motors had a goal of setting their sights on the home energy market and introduced the home battery pack known as, the Tesla Powerwall.

Tesla motors have been recognized for producing high-quality electric vehicles as well as well as their intelligence to reform and successfully thriving to rebrand current technologies. Tesla’s rebranding of residential-use batteries is in direction with their goal of reimagining existing products.

What is the Tesla Powerwall?

Tesla is one of the very few companies that makes small-scale batteries for home energy storage in the residential energy storage market. The Powerwall is described by Tesla is a “rechargeable lithium ion battery with liquid thermal control”. The initial release of the Powerwall launched in 2015, and a renovated Powerwall 2.0 was announced the following year in 2016.

The Tesla battery pack is an excellent match for solar panels, notably in the occasion of an off-grid project where a homeowner needs or desires to be purely independent of their utility. A solar storage system like the Tesla Powerwall permits you to maintain a sustained power supply during both day and night.

How does the battery work?

Similar to other energy storage products, the Tesla battery pack is designed to curate for day-today use at home, and usually integrated with a home solar panel system. The surplus electricity that is produced and not used in your home is then stored in the battery pack in lieu of being sent back into the electric grid.

Typically this process happens over a sequence of a day, when the sun is high in the sky and your solar panels are generating more electricity than you can use, the excess energy is saved in your Tesla Powerball. While the sun goes down, your solar productivity decreases and begins drawing in the electricity you stored during the sunniest part of the day. Virtually, the Powerwall helps you balance out and manage your electricity production over the course of a day.

Is it possible to go OTG (off the grid) with a Tesla Powerwall?

Benefits of installing a solar storage system in your home is a great way to have direct control of your electricity bill, but in essence doesn’t mean you are 100 percent separated from your utility. This means going “off the grid” with solar batteries is indeed more costly and intricate than you may believe. An individual Tesla home battery will administer only a few hours of backpack power – not practical enough to umbrella you on a cloudy day, or several days or weeks of harsh weather conditions.

The Tesla Powerwall warranty and how long does the battery last?

An unlimited 10-year warranty that predicts your battery is used for daily charging and draining is what comes with the Powerwall.

Alike with others, the Tesla batteries ability to hold charge depreciates over time. This does not indicate that this characteristic makes this product flawed. All batteries lose the capability to withhold a charge whether it’s a rechargeable AA battery, a home battery or an electric vehicle battery.

As Tesla says “Reliable Power Day and Night”. Let us help you go “off the grid” with the Tesla Powerwall!

Solar Energy Produce Water

New Technology Generates Drinking Water Out of Solar Panels

The solar energy market is always evolving. Since the green power movement started, about 20-30 years ago, we have witnessed so many improves in the solar technology. We now have solar panels that can generate enough power for your house, we have emergency backup batteries, solar roof tiles, and now we have solar purified water. A company called Zero Mass Water is responsible for the latest invention, using solar-like panels that create clean water from the air.
The panels absorb water molecules from the air, and then the molecules are treated with minerals to give them a fresh taste and filter the water. Each panel produces about 10 small water bottles a day and has a lifetime of about 10 years.

This amazing green technology might be the great next thing. Although it might be expensive for homeowners right now, the system will pay for itself in about 4 years since you won’t be buying water bottles anymore. Moreover, this technology can make a huge difference in countries that are in water-scarce situation.

Powerwall is Leading You Towards Power Independency

Elon Musk and his company Tesla never stop progressing. It feels like Musk made a resolution to save our planet, and he is moving towards the goal each year. The guy that gave us electric cars, solar energy for home and even offered to take us to the moon, have came up with another way to help you rely less on your grid power. With the new Powerwall technology, you can actually charge a big battery, that will provide you with power whenever there’s an outage in your area.

The Powerwall and Powerpack are used as a rechargeable battery stationary that is installed on the exterior wall of your house, and is connected to the solar panels system on your roof. These batteries are intended to be used as a backup power storage, for when the grid power isn’t working for any reason.

This might be the next step towards complete power independency for your house, as it’s providing a solution that grid companies cannot. Moreover, this could be the first step for a solution to providing solar power at night. Solar companies have always instructed their clients to stay connected to the grid, since solar power cannot be generated at night (when the sun as set). Having a power storage place is probably a good way to resolve that problem, making solar power absolutely independent, which will make it even more attractive since it would cut off your power bills completely.

Musk is so certain about the efficiency of the Powerwall Technology, that last month he offered it as a solution for Australia’s blackout problems. In fact, Elon Musk said that if the Powerwall batteries won’t fix the problem in 100 days, he will provide them all for free. The wager that musk set is this – Tesla will install 100 megawatt hours worth of Powerwall battery storage within 100 days, and if this won’t fix the blackout problems, they will do the whole project for free (The project worth is estimated US $25 Million).
