  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • Autumn Statement 2016: Any impact on energy?

    The  UK Government's Autumn Statement  provided a great opportunity to answer a number of key energy policy questions. Yet, apart from confirming that the carbon price will be capped at £18 t/CO2 until 2020 and that oil/gas tax breaks will be maintained, there was very little mention of energy. Granted this carbon price cap is likely to be welcomed as it provides the certainty and ...

  • Case study - Increased capacity & stringent effluent limits met in a small footprint

    This Idaho Wastewater Treatment plant’s two existing single-ring oxidation ditches were facing increased flows and a new tougher phosphorus limit of less than 2.3 kg (5 lb) of total phosphorus per day. In addition to a tight budget, the small amount of land available also hampered the city’s options. The consultant’s evaluation confirmed fine-bubble aeration “would ...

  • The three S approach to uncertainty

    Life seems to be getting more and more uncertain. We are being warned about a Brexit rollercoaster and the oil price, at least in percentage terms, seems to be doing a good impersonation of an elevator; up one minute, down the next. All this uncertainty makes decision-making complex , especially when they concern long-life assets. Against this background I have been thinking about the question of ...

  • How much does a residential solar system cost?

    The cost of a solar system depends on the size of the system that is built. Systems can be built so they are scalable. It is important to know what size the solar panel system is, how much electricity will be produced, and the price per watt. Each solar system will produce different amounts depending on how good the design is, what shading could reduce the systems daily production, and where the ...

  • Why Levelized Cost of Electricity is an important measurement in wind

    As the wind industry continues to grow, it is faced with much opposition, and a lot of misinformation is being shared. Some of the biggest myths around wind is that the costs of building and installing wind turbines are too high (compared to the costs of other energy sources) and that the industry is overly subsidized. Many anti-wind lobbyists point out that subsidies and tax benefits are the ...
