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 That supply has been replaced by wind, solar and natural gas.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.

Alternative Energy For Your Home – Produce Your Own Renewable Power

If you would like to build a home-made power generator like the solar panel and wind turbine at a shoestring budget, you will need a lot of specifics. The next few paragraphs can help you start the right way.

It is vital to reduce our usage of non-renewable resources of energy to avoid going deeper into world energy crisis. Renewable energy options refer to those energy solutions that could keep churning energy without exhausting the resources. These three types are what makes the renewable energy category: wind power, solar energy, and hydro energy.

While the sun energy is unlimited and free, utilize it. Solar power could be definitely employed at home. By using the sun energy, you may really cut down your power bill and contribute to a greener planet. It is possible to utilize sun energy for anything at your residence like baking, lighting, equipment, or heating and air conditioning.

The solar energy systems include several advantages apart from being cost-effective and environment-friendly. They are low on maintenance as a result saving your time and effort. Investment in sun power for your house makes a lot of sense. You receive a return on investment really soon and the systems become free to use. Remember that cooking using sun energy is considered incredibly healthy. All over the world, people have started utilizing sun power for their homes as a renewable power solution.

People have been using windmills ever since before the birth of Christ. The oldest kind of renewable energy is wind power. A long time ago, windmills helped tow boats and pump water but eventually they started to produce electrical power.

Wind power helps create a lot of electricity. That is the reason windmills and wind generators have always been in use. If used at home, wind energy helps cut down the utilization of standard power. Being a great resource of renewable energy, wind power will go a long way promising a bright future for next decades.

The next supply of an real renewable energy is the hydro or water power. Vehicles and plenty of utility devices may be run on water power converted into conventional electricity. Usually, hydro power is produced on a large scale.  It has been estimated that ninety  percent of the electricity produced by renewable resources is generated exclusively by hydro power.
