Wind energy is growing more economical and reliable. Vertical axis machines can help meet smaller, local needs for communities with limited resources.  These include pumping water, grinding grain, powering  workshops and in some cases, generating electricity. Learn about the two main types of vertical axis wind machines in this article: The lift type (eggbeater, helical and h-rotor) The Darrieus vertical axis wind turbines often has two or three thin, curved blades, depending on the model. These turn at higher speeds suitable for generating electricity but require much greater skill in design and engineering. The h-type is simply vertical blades. The … Continue reading →

Historic Vertical Axis Wind Machines: Lessons for Sustainable Energy

Most people are familiar with horizontal axis wind machines. These include the charming Dutch and Danish water pumping machines, the smaller sail windmills of Portugal, Greece and other areas, the iconic multi-blade water pumpers of the American west (millions sold), and the ever larger and more expensive three-blade wind turbines being used around the world to generate electricity. Hundreds of different wind machine designs have been proposed, built and tested and innovation continues to this day. The vertical axis wind machines are less well known. These had been invented and refined hundreds of years before the horizontal axis machines. Two … Continue reading →

Coal is one non-renewable energy source that people have long used. But due to industrialization and the increasing population, these sources of energy are decreasing at a fast rate. Additionally, non-renewable energy sources may have a negative impact on the environment. Due to these reasons, there was a need to develop a more sustainable and renewable energy source. Enter solar energy. States such as Colorado have made an effort to harness this non-depleting energy source, which is no surprise as it’s one of the sunniest states in the US. As technology advances, it has become easier for most Colorado residents … Continue reading →

The countries of the Middle East and North Africa (MENA) are known for their abundance of fossil fuels, yet they also have another energy resource at their fingertips – solar power. Some countries such as Saudi Arabia, which have great solar resources, are transitioning to utility scale solar energy production.  This allows them to export more of their fossil fuel instead of using it to produce power domestically. However, the decision to switch to solar power isn’t just to preserve oil resources for export. The countries in the MENA region are also experiencing increased demand for electricity due to rising … Continue reading →

The importance of renewable energy sources in the energy portfolio of any country is well known, especially in the context of energy security and impacts on climate change. The growing quest for renewable energy and energy efficiency in the Gulf Cooperation Council (GCC) countries has been seen by many as both – a compulsion to complement the rising energy demand, and as an economic strength that helps them in carrying forward the clean energy initiatives from technology development to large scale deployment of projects from Abu Dhabi to Riyadh to Muscat. Current Scenario The promotion of renewable energy is becoming … Continue reading →

Morocco, being one of the largest energy importers in MENA, is making concerted efforts to reduce its reliance on imported fossil fuels. Renewable energy is an attractive proposition as Morocco has almost complete dependence on imported energy carriers. In 2022, Morocco spent around US$13.5 billion on all energy imports (crude oil and oil products, coal, natural gas and electricity). Annual electricity consumption in Morocco was 38 TWh in 2022, and is steadily increasing at a rate of around 7 percent each year. The major sources of renewable energy in Morocco are solar and wind power. Wind energy potential is excellent … Continue reading →

Germany, Europe’s largest economy, is aiming to generate 80 percent of its energy from renewable sources by 2030. Additionally, Germany is currently in the process of abandoning nuclear power by 2022 and is making plans for a long-term exit from the use of coal. This change signifies progress for Europe as a whole. According to a research from the Fraunhofer Organization of Applied Science, hydroelectric, solar, wind, and biomass energy generated 275.2 terawatt hours (TWh) of electricity in 2024 which accounted for 62.7 of total electricity generation in the country. The share of green energy in Germany’s power production has … Continue reading →
