Nevada goes for more renewable energy projects

E-mail Print PDF

Nevada is one of the nation's renewable energy leaders. In 2017, Nevada ranked second in the nation in electricity generation from geothermal energy and fourth in utility-scale generation from solar energy according to the official EIA report. These two renewable energy sources supplied 19% of Nevada’s utility-scale net electricity generation.

Nevada is making further steps to add more renewable energy to its portfolio.  A few days ago it was reported that The Public Utilities Commission of Nevada (PUCN) approved NV Energy's Integrated Resource Plan, which will bring 1,001 megawatts of new renewable energy projects to Nevada, including the 100 megawatts of battery storage capacity.

Three of these renewable energy projects will be located in northern Nevada and three will be located in southern Nevada. All projects are expected to be completed and working by the end of 2021.

Hydropower in Norway- Quick introduction

E-mail Print PDF

Norway is by far the largest producer of hydroelectricity in Europe, and also the sixth largest producer in the world.  This rich Scandinavian country is blessed with plentiful hydro resources and is certainly making the most of it. 

Norway has very long history of using hydropower resources, for instance Hammeren power station in Maridalen outside Oslo that become operational in 1900 is still delivering electricity, after more than a century.

According to the most recent reports 98% of country's electricity production is based on hydropower. At the end of 2016, Norway’s hydropower resources combined for over 31 GW installed capacity.

How to use sunlight to produce hydrogen?

E-mail Print PDF

Many energy experts believe that hydrogen is one of future's top fuels. There are many ongoing researches with the purpose of finding the cleanest and the most efficient way to produce hydrogen. One of the most interesting techniques is water splitting by using the sunlight.

Water splitting by using sunlight is really a form of artificial photosynthesis where sunlight is used to produce hydrogen from water. How does this process work?

First we have water splitting devices that are made of light-absorbing materials. These materials are capable to absorb different parts of the solar spectrum ranging from infrared to ultraviolet light. Once the light is absorbed by these materials it builds an electrical voltage.

How to ensure maximum wind farm production?

E-mail Print PDF

Wind power use is rapidly growing all over the world. In many corners of the world you can see wind turbines with gigantic rolling blades harnessing the clean power of the wind and converting it into electricity.

How to improve productivity of these wind farms? Many would likely say by adding more wind turbines but this isn't always the case, in fact it can even lead to decreased production. Just getting the numbers up, doesn't always result in getting the more power.

Why is that? We have to start with the premise that each wind turbine has been designed for use by themselves and in wind farm it is almost never used by themselves anymore. Wind turbines are now used in groups of hundreds and even thousands and in large installation with the group of thousand turbines each one may not fulfill its full potential.

Is wood really a low carbon fuel? EU think it is

E-mail Print PDF

Europe's renewable energy directive will aim to double Europe's renewable energy consumption by 2030. The downside to this directive is the fact that European officials will promote the use of wood as a renewable, low carbon fuel.

Under this directive wood should be treated as a low-carbon fuel, which could eventually lead to great harm to the world's forests because the magnitude of using wood as biofuel will likely be far greater than it is now.

Many researchers fear that this qualification will lead to massive new cutting of the world's forests. It has been calculated that the additional wood equal to all of Europe's existing wood harvests will be needed just to supply 5 percent of Europe's energy.

Some researchers estimate that using wood for energy will likely result in 10 to 15 percent in greenhouse gas emissions from Europe's energy use by 2050.
