Americans used more clean energy in 2016

Americans used more renewable energy in 2016 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory. Overall, energy consumption was nearly flat.

Each year, the Laboratory releases energy flow charts that illustrate the nation’s consumption and use of energy. Americans used 0.1 quads (quadrillion BTU), more in 2016 than in 2015. A BTU, or British Thermal Unit, is a unit of measurement for energy; 3,400 BTU is equivalent to about 1 kilowatt-hour.

Prices for photovoltaic panels have fallen dramatically over the past decade, contributing to solar energy’s rapid growth, which rose by 0.15 quads or 38 percent in 2016, with significant additions in the electricity, commercial and residential sectors. “Two thirds of that increase was in the electric sector,” said A.J. Simon, group leader for LLNL’s energy program. “These are large installations of thousands of solar panels, usually in the desert.” Installations on the roofs of homes and warehouses account for the rest of the additions.

Likewise, more wind power is contributing to the nation’s utility grid. Use of wind power rose by 19 percent or 0.33 quads. “Generous incentives for renewable energy, combined with improved ‘know-how’ in siting and building wind farms, has led to a favorable environment for growth in this sector,” Simon said.

Coal use decreased by 9 percent to 14.2 quads, mostly due to decreased coal supply to the electricity sector. That supply has been replaced by wind, solar and natural gas. Overall, natural gas use rose by 1 percent to 28.5 quads.

Energy use in the residential, commercial and industrial sectors all declined slightly, while consumption of fossil fuels in the transportation sector rose by 0.5 quads or 2 percent.

All energy use results in some losses, shown on the charts as rejected energy. This energy most often takes the form of waste heat, such as the warm exhaust from automobiles and furnaces. The efficiency of the nation’s cars, lightbulbs and factories determines how much waste heat is produced, and how much of fuel and electricity can be put to productive use.

This year marks two changes to the energy flow chart. The Energy Information Administration has changed the way it analyzes and reports renewable energy use, and those changes are reflected in the 2016 chart as well as a revision to the 2015 analysis. Additionally, the estimate of efficiency of the industrial sector has been reduced from 80 percent to 49 percent to align with recent analysis at the DOE’s Advanced Manufacturing Office. LLNL reports all year-over-year changes on a basis consistent with the new methodology.

3 Simple Things People Should Do to Consume Less Energy and Save it For Future Generations

Consume less energy and save it for future generations. We’re always hearing we should, but how?

Here are three simple steps that we can take individually to consume less energy — and if we do that, we save it for future generations… and we are saving money. Take these simple steps and start saving today.

  1. Turn off lights — by far the easiest way to save electricity and save money. Turning off lights as you leave the room alone saves you a lot on your electric bill. Then, as you turn off lights, you see ways to…
  2. Unplug unused electronics — this is the electricity waster that many people do not even know exists. Many of today’s appliances, both large and small, and electronic devices in our homes draw a small amount of power even when switched off. This “phantom power” drain comes from VCRs, televisions, satellite and cable boxes, DVRs, stereos, computers, printers, kitchen appliances, clocks and clock radios, cell phone and portable music player chargers, laptop chargers… almost anything plugged into wall power. This is especially true if the device has a remote control; the circuitry that responds to the remote must ALWAYS be on — and drawing power – or the remote will not work. As much as three quarters of the electricity used to power many of these devices goes through them while switched off.
  3. Switch to energy saving bulbs — by switching to energy saving bulbs technology from traditional incandescent type lamps, you can save energy and save money on your energy bills. Using today’s new energy saving bulbs technologies: Compact Fluorescent Lamps (CFLs), and Light Emitting Diode Lamps (LED or L.E.D.), you can save as much as 80% on the energy you use to light your home — and less energy used is less money out of your pocket plus it reduces the resources needed to create that power.
CFL Bulbs The important thing is always think about ways to consume less energy. Switch off or unplug anything you’re not using. You’ll save a great deal of energy, reduce your utility bill, reduce resources used to create the power, and save it for future generations of people on our planet. Even if you create the power with your own wind and solar generators, if you use less, you will have more for other things — and for future generations.

Dan Davenport wants the world to be a greener place — intelligently. If we use the energy resources we already have wisely, and exploit viable, renewable energy sources, it is good for the planet, we will save money, and, not only we, but future generations, can continue to live comfortably.

Solar Power Energy – Supplying A Greater And Greener Energy

Solar Power Energy has forever been readily available. Up to now, we’ve not really mastered the way to utilize solar energy power. A Solar Energy power system can be utilized by anybody to meet all of their electrical power necessities, supply back-up power, and even just an aid for the standard power grid connection to a power company.

It’s perfect for distant areas in which electrical power is not available or perhaps too costly.Thermal solar energy power can be used to create heat. Typically seen in water heaters, solar-heated pools, and also home heating systems , thermal energy works through utilizing sun’s heat and then switching it to a new channel.

A simple thermal power system used in hot water heaters is made of absorbent solar power panels linked to pipes by which antifreeze can move. As sunlight reach the solar panels, these panels consequently heat the moving water, which in turn shift heat to domestic water.

In solar pools, tiny discs can lay on the top of water, harnessing sun rays then moving the heat towards the pool water. For additional substantial solar energy production, solar systems come into play.

The movement of the electrons makes an electrical current, which in turn may then be routed to an inverting system and be utilized just like any other electrical power.

This sustainable energy provided by the sun may be manufactured to accomplish almost everything that various other types of heat as well as electrical power could deal with.

As the sun is a pretty dependable way to obtain power in sunnier areas, this makes solar energy power an important player down the road of energy technologies and usage.

Possibly the best advantage of solar energy power is that customers are able to supply their very own power, so minimizing the necessity to depend upon power utility companies.

Remember every year, electrical power costs increases, making us to spend greater expense each month. Together with solar energy power, on the other hand, climbing electrical power costs may not have a greater impact on people.

Many people could possibly have second opinion of making use of solar energy power systems due to the price and high expense in buying and setting it up. Obtaining solar panels set up in your household may well often extravagant.

Even so, if you see the huge benefits along with the full proportion of personal savings you can get annually, using a solar energy system could be a lot better than having to pay power companies simply to obtain electrical power.

Using electrical energy supplied by solar energy offers a lot of advantages. Besides encouraging eco-friendliness, what’s more , it supports consumers in preserving upon electricity fees. Solar power energy is likewise green which could result in energy power conservation, getting a way of making sure that non-renewable fuels don’t promptly run out.

The significance as well as benefits of Solar Energy and its purposes weren’t actually rejected from the prehistoric era. Sunshine assists crops to be able to make food during the process of photosynthesis.
