The Air Force's first landfill gas generators went into operation in 2006 at HILL AIR FORCE BASE, Utah.
The facility includes three generators and produces 2.3 megawatts of electricity per year.
The Air Force's second landfill gas generation facility opened in 2013 at Joint Base Elmendorf-Richardson, Alaska.
It houses five generators and creates 7 megawatts of electricity per year, the highest-producing single renewable energy project in the Air Force.
The Air Force Civil Engineer Center's Energy Directorate Has studied the Air Force Civil Engineer Center's Energy Directorate Has studied more than 600 recorded Air Force landfills to search for similar opportunities.
It's now seven years since the commissioning of the 2nd landfill gas facility.
The successful project, along with one at Hill Air Force Base, Utah, has saved the Air Force millions of dollars in power bills.
It's this type of renewable energy that increases resiliency for the Air Force facility energy program because it operates 24 hours a day, seven days a week.
Landfills generate methane gas for an average of 30 years.
Once it tapers off, engineers will supplement the plant with natural gas to continue power generation.
Landfill gas is a complex mix of different gases created by the action of microorganisms within a landfill Natural gas (also called fossil gas) is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
Renewable Natural Gas (RNG), also known as Sustainable Natural Gas (SNG) or biomethane, is a biogas which has been upgraded to a quality similar to fossil natural gas and having a methane concentration of 90% or greater.

Building Costs Can Be Saved 5 By Adopting These Construction Waste Recycling Methods
Here are 5 construction waste recycling methods through which sustainable builders achieve recycling and reuse of building waste in construction projects.
1 – Segregating timber waste on site and sale for re-use
Large timbers from older or unique structures can be salvaged and reused as structural elements in new buildings.
Lumber to be reused as a structural element, would need to be re-certified by a lumber inspector first.
Some firms offer certified lumber inspectors that can grade lumber for use on site.
2 – Storing reusable bricks and roof tiles from demolition phase, for use in later phases.
Many people prefer the beauty of old bricks and roof tiles for new construction.
There are monetary savings in doing this, as well as the satisfaction of performing an environmentally friendly act.
3 – Segregating metal waste on site
Metal waste is generally categorized into Ferrous and Non-ferrous types.
Prices paid do vary month by month.
but for iron scrap are in the range £100 and £150 per tonne.
The value of non-ferrous demolition materials at the gate of a metal scrap dealer varies between £400 and £3,600 per tonne.
4 – Segregating paper and cardboard waste and baling on site prior to disposal
Construction waste includes a high proportion of packaging waste, especially during the fit-out stage.
If this was sent to landfill it would cost over £100 per tonne in landfill disposal fees at the gate.
By sending it for recycling you are unlikely to be paid much, but will save the landfilling charges.
5 – Test Soil Using ‘CL:AIRE’ and if Satisfactory Avoid the Material Carted Off-Site Being Considered to be a Waste
Clean soil from excavation can be tested using ‘CL:AIRE’ methodology and then if satisfactory be dealt with as “Material Transfers to be reused on another site”.
That means that a sustainable alternative to disposing of waste in landfill sites is then possible.
There are many concepts for reuse and recycling of construction and demolition waste.
The Gas Flare Secret Why Flaring is 34 Times Better Than Not Flaring
A gas flare, alternatively known as a flare stack, is a gas combustion device used in industrial plants such as petroleum refineries, chemical plants, natural gas processing plants as well as at oil or gas production sites having oil wells, gas wells, offshore oil and gas rigs and landfills.
Keep watching to learn why gas flares reduce climate change.
Flare stacks are primarily used for burning off unwanted flammable gas released by pressure relief valves, for the following reasons:
1 - Flare stacks are often used for the planned combustion of gases over relatively short periods such as when carrying out new gas plant start-ups.
2 - During unplanned over-pressuring of plant equipment, including emergency breakdown of equipment.
3 - During plant shutdowns, which are usually for equipment maintenance.
4 - In the case of landfill gas, flaring is done when the amount and quality of the landfill gas is too low for economic use.
5 - To reduce climate change.
Methane's estimated global warming potential is 34 times greater than that of Carbon Dioxide (CO2).
Therefore, to the extent that gas flares convert methane to CO2 before it is released into the atmosphere, they reduce the amount of global warming that would otherwise occur.

The 10 Most Deadly Plastics Found Most Often in Rivers and Lakes
The 10 worst plastic pollutants in rivers and lakes ranked by prevalence are:
1 - Plastic bottles and lids.2 - Food wrappers (crisp packets and sweet wrappers).3 - Cigarette butts4 - Sanitary items (nappies, sanitary towels, tampons and wet wipes).5 - Plastic or polystyrene takeaway containers.6 - Cotton bud sticks7 - Plastic or polystyrene cups.8 - Smoking-related packaging.9 - Plastic straws, stirrers and cutlery.10 - Plastic bags.
The Plastic Rivers report, published today (8 April 2019) in association with Plastic Oceans UK, has analysed data from nine studies of freshwater sources across the UK and Europe, revealing the worst ten plastic pollutants in the UK’s rivers and lakes.
It ranked types of macroplastic by prevalence, focusing on consumer items and excluding items relating to fishing, agriculture and industry.
Plastic bottles are the biggest contributor to freshwater plastic pollution, followed by food wrappers and cigarette butts, the research found.
Much of the plastics focus to date has been on the shocking impact pollution is having on ocean species, but up to 80% of the plastic in our seas actually comes from rivers. Understanding the situation in freshwater environments is an essential but often overlooked factor in stemming the tide of plastic reaching our oceans.
The Plastic Rivers report shows that the products we buy every day are contributing to the problem of ocean plastic. Our discarded plastic enters rivers from litter generated by our on-the-go lifestyle and items we flush down our toilets. This throw-away approach is having much more serious consequences much more serious consequences than previously imagined, and the report shows really simple ways to avoid this problem and stop plastic pollution.
Click the link above to see the full article, or go to CIWM Online and search "plastic pollution".
Worldwide reliance on disposable plastic packaging is overwhelming our planet.
By 2050, the oceans will contain more plastic than fish by weight.
Plastic pollution is toxic to human health.
Even babies are born pre-polluted.
Plastic pollution and climate change are parallel global emergencies.
Plastic is a petroleum product; to truly divest from fossil fuels, we must reduce our collective plastic footprint. via www.plasticpollutioncoalition.org
Why is Plastic Litter and Pollution Growing So Fast?
The world population is living, working, vacationing, increasingly conglomerating along the coasts, and standing on the front row of the greatest, most unprecedented, plastic waste tide ever faced.
Washed out on our coasts in obvious and clearly visible form, the plastic pollution spectacle blatantly unveiling on our beaches is only the prelude of the greater story that unfolded further away in the world’s oceans, yet mostly originating from where we stand: the land.
For more than 50 years, global production and consumption of plastics have continued to rise. An estimated 299 million tons of plastics were produced in 2013, representing a 4 percent increase over 2012, and confirming and upward trend over the past years.
(See: Worldwatch Institute – January 2015). In 2008, our global plastic consumption worldwide has been estimated at 260 million tons, and, according to a 2012 report by Global Industry Analysts, plastic consumption is to reach 297.5 million tons by the end of 2015. via plastic-pollution.org
Is More Recycling the Solution?
Not really. Recycling does not really address plastic pollution, since recycled plastic is "properly" disposed of. Whereas, plastic pollution comes from improper disposal.
Since the ocean is downstream from nearly every terrestrial location, it is the receiving body for much of the plastic waste generated on land. Several million tonnes of debris end up in the world's oceans every year, and much of it is improperly discarded plastic litter.
The first oceanographic study to examine the amount of near-surface plastic debris in the world's oceans was published in 2014. It estimated that at least 5.25 trillion individual plastic particles weighing roughly 244,000 tonnes (269,000 tons) were floating on or near the surface.
A Seriously Damaging Effect at the Bottom of the Food Chain
Because it comes in sizes large and small, polluting plastics even affect the world's tiniest organisms such as plankton.
When these organisms become poisoned due to plastic ingestion, this causes problems for the larger animals that depend on them for food. This can cause a whole slew of problems, each step further along the food chain. Plus, it means that plastic are present in the fish that many people eat everyday.
Most of the litter and pollution affecting the world's oceans derives from plastics. This is having had terrible consequences on many marine species, which can lead to consequences for those that eat fish and marine life for nutrients – including people. via www.conserve-energy-future.com
Sources of Ocean Plastic - Mismanaged Waste and Inadequately Disposed Waste
Mismanaged waste is material which is at high risk of entering the ocean via wind or tidal transport, or carried to coastlines from inland waterways.
Mismanaged waste is the sum of material which is either littered or inadequately disposed.
Inadequately disposed and littered waste are different, and are defined in the sections below.
Inadequately disposed waste is that which has the intention of being managed through waste collection or storage sites, but is ultimately not formally or sufficiently managed.
This includes disposal in dumps or open, uncontrolled landfills; this means the material is not fully contained and can be lost to the surrounding environment.
This makes it at risk of leakage and transport to the natural environment and oceans via waterways, winds and tides. via ourworldindata.org

Australian Renewables On Track For 78% By 2030 On Current Trends
Specifically, according to Green Energy Markets, if Australia maintains its current record rate of both rooftop solar installations, as well as wind and solar farm construction commitments that have prevailed since 2017, then renewable energy would account for 78% of electricity supply across Australia’s west and east coast main grids by 2030 — up from their current contribution of 22.5% in October.
October saw the Australian solar industry install another 150 megawatts (MW) of residential and business solar, a new record, 76% higher than the monthly average of 2017, which itself was a record year for installations.
So far this year, rooftop solar installations have reached 1,243 MW for the year so far. Meanwhile, a total of 412 MW worth of large-scale wind and solar projects committed to construction in October, bringing the year-to-date total commitments up over 3,200 MW. via CleanTechnica
Projecting 2018 Trends and Macroeconomic Conditions: What to Expect for Renewable Energy Projects in 2019
Renewable energy projects were marked by distinctive trends and characteristics in 2018:
a frothy.
A market driven by a crush of liquidity and a shortage of project supply
a highly competitive environment among investors and lenders for an inadequate supply of projects.
They also predict continued focus on alternative off-take structures with shorter tenors, such as corporate PPAs and energy derivatives, and unconventional credit, such as community customers.
Shoots of energy storage solutions sprouting from the ground as stand-alone facilities and add-on’s are likely for wind and solar projects. via 2018 Trends
Top Trends To Watch In Renewable Energy In 2019
This year has seen several major policy changes in renewable energy, especially in solar.
China surprised everyone in June by announcing that it would not issue approvals for any new solar power installations in 2018 and would also cut the feed-in tariff subsidy.
In February, the U.S. imposed tariffs on imported solar cells and modules, creating uncertainty in the U.S. solar market.
The solar market globally is set to adapt to those industry disruptions next year. Together with continued declines in solar and wind costs, 2019 could be a brighter year for the U.S. solar and renewable energy markets, analysts and industry professionals say. via OilPrice.com
Big Data Analytics, Machine Learning and AI in the Renewable Energy Sector
Analytics, Machine Learning, and artificial intelligence (AI) are used to interpret the past, optimize the present and predict the future.
The energy sector heavily depends on optimization and predictions for energy production, energy grid balancing, and consumption habits.
Additionally, the energy industry produces massive amounts of data. To turn this data into insights to improve productivity and cut costs, major energy players are turning to AI. via AI Trends
