Solar Energy has Little Impact on Birds
People are not worried about the pollution coming from the renewable energy sources, because most of them do not produce significant amounts of pollution. The supplies, the process of how the supplies come to the source and the demolishing machines used to erect these renewable energy sources are the true culprits wreaking havoc environmentally. For instance, older wind turbines have a negative ...

Oceans of Energy
Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...

Competition in Wind Power, Outcomes for the future
Without a doubt, wind power is taking the lead as not only a renewable energy with a much lessened environmental impact, but it is also edging out the competition from fossil fuels with the distinct ability to lessen the impact on the wallet. Fossil fuel consumption, headed by traditional fuel sources such as oil and natural gas, are falling to the way side as having a significant difference in ...

Studies on performance characteristics of a solar parabolic trough concentrator with a variable area absorber
The design of a suitable absorber that incorporates an efficient heat transfer augmentation technique is one of the vital parameters that affect the performance of a solar parabolic trough concentrator (PTC). The variable area absorber discussed in this paper provides appreciable augmentation in heat transfer without increasing the pressure drop materially and thus helps in enhancing the ...

Decentralised operation of residential energy resources in the smart grid
In the future smart grid, improvement of power system economic cost effectiveness by suitable integration of distributed energy resources (DERs) is a critical challenge. An agent–based framework is proposed in this paper for developing suitable control strategies for operations of four different types of residential–level DERs, which are storage devices, photo voltaic systems, and two ...

A hybrid wind/solar/diesel stand alone system optimisation for remote areas in Algeria
While Algeria has an important potential of wind and solar energies, their share in the primary energy supply is relatively low compared to the fossil energy. In this paper, we propose to carry out a techno–economical study of a hybrid stand alone system in order to draw the attention to the feasibility of such systems. For this purpose, sites of Hassi–R'mel and Adrar have been ...

Calibration of selected pyranometers and satellite derived solar radiation in Puerto Rico
Knowledge of solar radiation at the ground surface is valuable for many disciplines. In this study, ground–based sensors at Fortuna and Mayaguez, Puerto Rico, were used to calibrate daily–integrated satellite–derived solar radiation. The calibration equations yielded R² values of 0.88 and 0.83 at Fortuna and Mayaguez, respectively. A regression equation was also derived ...

Insurers Have Huge Role As Clean Energy Investors
Conversations about climate change and the insurance industry usually focus on catastrophic storms and their damaging financial ripples for insurance providers. Given skyrocketing extreme-weather losses in recent years, it’s surely a legitimate issue that should be making insurers re-think their business models. But insurers have another important role on the climate issue, which is how to ...

Effects of Solar Energy On Wildlife
In America’s southwest, the high potential for harnessing the solar energy as a renewable source is exponentially large. In addition, in the southwest the numbers of endangered species of birds and mammals is also large. What will the impact be on these birds and animals, as renewable energy sources are operating? How can Solar Energy be Detrimental to Wildlife? Studies performed on the ...

Blue-Green Opportunities: Energy Efficiency and Jobs Impacts in the U.S. Manufacturing Resurgence
U.S. manufacturing—and the jobs that go with it—have been steadily increasing since 2010. As President Obama mentioned during last month’s State of the Union address, the U.S. economy added 568,000 new manufacturing sector jobs between January 2010 and December 2013. Meanwhile, industry—of which manufacturing is the largest component—reduced its energy-related CO2 ...

Sure Green Island, Palawan, Phillipines - Case Study
Our PP20 Power Pallet was Installed in Green Island, a small village island located about 14 kilometers off the coast of Roxas, Palawan, in the Philippines. The project is being developed by Solutions Using Renewable Energy (SURE) who are building a microgrid system tying a 2.5 kW solar array and a 5 kW wind turbine to our 20 kW Power Pallet. This grid is supplying power not only provide light ...

4 Insights on Unlocking Finance for Clean Energy Access in Africa
January heralds the start of not just a new year, but a new decade: the U.N. Decade of Sustainable Energy for All. In declaring the Decade, the U.N. has urged its members to help “make universal access to sustainable modern energy services a priority.” One of the regions where universal access to clean energy remains a pressing challenge is sub-Saharan Africa, where roughly 590 ...

Top 5 Climate and Energy Stories for 2014
The U.S. energy picture has shifted dramatically in recent years. The country is currently enjoying booming domestic energy production from multiple sources. And yet, signs of uncertainty abound, especially with mounting climate risks and some energy sectors thriving more than others. We will be watching President Obama's State of the Union address on Tuesday to hear the approach that the ...

How Green Tariffs Can Benefit Utilities and Consumers
The challenges facing the electricity sector in the U.S. have been widely discussed in the last year—issues ranging from evolving pollution controls to slow growth in demand. In particular, many utilities see the rise of small-scale, distributed solar power as a threat to their businesses. Anxious about losing customers, utilities are moving to reform self-generation rules so that ...

Global solar installation will reach 49 GW in 2014
Global solar installation will reach 49 GW in 2014 NPD Solarbuzz predict the demand of solar module will likely to reach 49 GW next year. And they also estimated 36GW capacity of solar panel will end the solar installation in the year of 2013. The grow rate of next year’s solar installation will more than30% as the prices of solar panel still go down and become more stable. China, Japan ...

A predictive algorithm for minimising dead–time distortions in sine–wave VSI with L–C output filter
In many applications, single–phase sine–wave inverters are operated with low–pass filters at the output to deliver a low–distortion sinusoidal voltage to the load. In such cases, it is essential that the output be as close to a sinusoid as possible. However, conventional bridge–type inverters, which must be operated with some dead time, suffer from dead–time distortion problems. This effect ...

Power Sector Opportunities For Reducing Carbon Dioxide Emissions: Minnesota
President Obama announced the first-ever National Climate Plan for the United States in June 2013. Under the plan, the U.S. Environmental Protection Agency (EPA) will set carbon pollution standards for power plants. In September 2013, EPA introduced emissions standards for new power plants and is expected to announce standards for existing plants in 2014. Once EPA establishes those standards, ...
