It is necessary to optimize the performance of existing, aging wind turbine plants so as to reduce their operational and maintenance costs. The reliability of turbines decreases with age and the unavailability of or difficulty in finding the required spare parts for old models can greatly increase the operations and maintenance cost. The biggest challenge … Continue reading Top 3 ways to reduce the cost of wind turbine operations and maintenance

Concentrated Solar Power would need to meet 8%-10% of global electricity demand by 2050
The best sites are between 10° and 40°, South or North. As you can see in the chart below, this makes a huge difference, a CSP in Chile might cost half as much as one in Spain. Locating a plant with a solar irradiance of 2,700 kWh/m2 would decrease the generation cost by 25% compared with … Continue reading Concentrated Solar Power would need to meet 8%-10% of global electricity demand by 2050

Misconceptions on wind energy costs in UK
A new survey commissioned by RenewableUK has revealed that the UK public have considerable misconceptions about the cost of wind power, believing subsidies to be 14 times more than they actually are. Marketing research firm OnePoll carried out the survey and questioned 2,000 adults in the UK. According to survey, the average customer thinks … Continue reading Misconceptions on wind energy costs in UK

Photovoltaic reduces costs
China’s large PV market share is mostly involved with technologies that are well-established. Many PV module manufacturers have the ability to buy turnkey production lines. And while China’s PV manufacturers get a lot of respect for what they do, their well-established product dumping policies result in production with not a lot of gross margin, if … Continue reading Photovoltaic reduces costs

Solar energy and wind power will be the cheapest forms of energy
A new study demonstrates that an energy system based completely on renewable forms of energy will be economically viable in the future. Research done at Lappeenranta University of Technology (LUT) shows that it will be worthwhile for North-East Asia, and China in particular, to switch to a completely renewable energy system within 5–10 years. … Continue reading Solar energy and wind power will be the cheapest forms of energy

The cost of wind energy and solar power keeps dropping
A new study from the International Renewable Energy Agency laying it out in detail. Large wind power farms got cheaper between 2010 and 2014. Large-scale solar power got a lot cheaper. And at least some renewable plants are even becoming competitive with new fossil-fuel plants: The chart shows the “levelized cost of electricity” for different … Continue reading The cost of wind energy and solar power keeps dropping

Renewable energy now cost advantageous, especially when cost of pollution is factored in
The cost of generating power from renewable energy sources has reached parity or dropped below the cost of fossil fuels for many technologies in many parts of the world, the International Renewable Energy Agency (IRENA) revealed in a new report today. The landmark report, Renewable Power Generation Costs in 2014, concludes that biomass, hydropower, … Continue reading Renewable energy now cost advantageous, especially when cost of pollution is factored in

Renewable energy costs in 2014: Wind energy and solar power now cheaper than fossil
The cost of generating power from renewable energy sources has reached parity or dropped below the cost of fossil fuels for many technologies, the International Renewable Energy Agency (Irena) has revealed. Irena’s “Renewable Power Generation Costs in 2014” report concludes that biomass, hydropower, geothermal and onshore wind are all competitive with or cheaper than coal, … Continue reading Renewable energy costs in 2014: Wind energy and solar power now cheaper than fossil

Levelized Cost Of Electricity: Solar power and wind energy are rapidly becoming competitive
Solar power and wind energy are rapidly becoming competitive with conventional electric generating technologies like natural gas and coal. At least that is what many of Wall Street’s most esteemed investment firms seem to be telling anyone willing to listen to them. Last week, Diane Cardwell, a reporter at the New York Times, did just … Continue reading Levelized Cost Of Electricity: Solar power and wind energy are rapidly becoming competitive

Solar Energy Will Be as Cheap as Fossil Fuel Energy by 2016
A new study on solar energy from Deutsche Bank bears very good news. Thanks to technology and innovation, solar energy will be just as cheap as energy from fossil fuels by 2016. That’s basically tomorrow, and it’s awesome. We have a few people to thank for this encouraging turn of events. One is Uncle Sam. … Continue reading Solar Energy Will Be as Cheap as Fossil Fuel Energy by 2016

Wind power is more cheaper than gas
It’s no surprise that if environmental costs are considered, renewables—particularly wind power—are a far better bargain than coal power. But it might surprise many that according to a new such analysis, nuclear power lags far behind wind energy and even hydroelectric power in its economic impact, at least in the European Union. Energy costs are … Continue reading Wind power is more cheaper than gas

Onshore wind energy cheaper than coal, nuclear and gas
Producing onshore wind energy is cheaper than coal, nuclear and gas, the European Wind Energy Association (EWEA) has claimed. Based on EWEA’s analysis of the data in the report, onshore wind has an approximate cost of EUR 105 per megawatt hour (MWh) which is cheaper than gas (up to EUR 164), nuclear (EUR 133) … Continue reading Onshore wind energy cheaper than coal, nuclear and gas
