With solar installations continuing to grow in the residential, commercial and utility segments, one of the biggest criticisms of solar technology — that it is an intermittent source of power and does not generate electricity once the sun has set — is now coming up against the benefits and values of combining battery storage with solar PV systems. Combining banks of batteries with solar systems has primarily been an application occurring in the off grid market for those buyers living in more remote areas who have not had access to centralized electricity grid service. The market for combining battery storage with solar has historically remained small due to, among other things, a lack of integration of varying parts of solar with storage systems. Another reason for the market’s small size is the belief that electricity pricing from electric utilities will remain reasonable and power from the grid will remain reliable.
Italy’s Enel Green Power is entrenching itself as a global leader in hybrid renewables engineering and construction with another announcement of a global first. In November, the company revealed that it would build a €15 million, 5-MW biomass plant to boost the Cornia 2 geothermal plant’s 13-MW capacity in Castelnuovo Val di Cecina, Tuscany, as “the first plant in the world to use biomass to heat geothermal steam and boost the energy efficiency and output of the geothermal cycle.”
Manhattan’s flood of green protesters had climate-change skeptics seeing red Sunday on 21st of September 2014. “Their love for the Earth is so real, they couldn’t even use a trash can,” tweeted a disgusted @chelsea_elisa, along with a photo of an overflowing trash can in Manhattan, after tens of thousands of marchers invaded the city on fleets of smog-producing buses. Legions of demonstrators frustrated by international inaction on global warming descended on New York City on Sunday, marching through the heart of Manhattan with a message of alarm for world leaders set to gather this week at the United Nations for a summit meeting on climate change.
Natural herbal remedies are drawing the attention of many traditional medical practitioners to rapidly recognize the ability of the hundreds of thousands of known herbs that have the ability to treat and prevent various human and animal illnesses, as well as properties that can enhance mental attitude, appearance, and performance.
In the fast paced world that we live in it can be easy to neglect our health and wellness. We’re so busy racing through our day to day lives – family, friends, work, social engagements – that we don’t take the time to look after ourselves. It’s really no wonder that so many of us are tired and run down. What are some simple things that we can do to improve our quality of life?
Third generation photovoltaic cells are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31-41% power efficiency for singlebandgap solar cells. This includes a range of alternatives to the so-called "first generation solar cells" (which are solar cells made of semiconducting p-n junctions) and "second generation solar cells" (based on reducing the cost of first generation cells by employing thin film technologies). Common third-generation systems include multi-layer ("tandem") cells made of amorphous silicon or gallium arsenide, while more theoretical developments include frequency conversion, hot-carrier effects and other multiple-carrier ejection.
World Environment Day on 06.06.2014 was important for European nuclear energy policy, and the triggering issue was in Ukraine. No, it was not because of the G7 meeting talking about the consequences of energy dependence in the shadow of the political problems in Ukraine. The G7 did not really address nuclear, because they are aware nuclear cannot really help them out and the risks of nuclear power in conflict areas are not a strong issue on their agenda.
