Why is natural gas better than coal boilers? - 0 views

  •  
    The economic development of one country is dependent upon the ability of the authorities to set up a highly suitable, competitive and reliable electricity sector. Why is natural gas better than coal boilers? Only when there is extreme environmental pressure or substantial reduction in loads that conversion from coal to 100% natural gas is possible. Not until the 20th century until natural gas was used for production of energy, it was dismissed as a useless byproduct of crude oil production until then. But now natural gas accounts for 23 percent of the world's energy consumption and still growing. The International Energy Agency predicts that the demand for natural gas will grow by approximately 44 percent through 2035. Natural gas is the cleanest-burning conventional fuel not to mention it has been one of the most economical energy sources. It is an environmentally friendly and efficient source of energy. It produces lower levels of greenhouse gas emissions than heavier hydrocarbon fuels such as coal and oil. Natural gas fuels electric power generators, heats buildings and is used as a raw material in many consumer products, such as those made of traditional plastics. However, natural gas has never been a cheaper fuel than coal. Coal is one of the longest-used and is considered as the most abundant fossil fuels on Earth. Coal mining has been going on since then 17th century. Coal burning boilers have also been around for a long time, and while they may not always be popular, these machines have some definite advantages in terms of costs and simplicity. Because it is the most abundant it is the cheapest form of fossil fuel to burn. But coal boilers on the other hand have harmful effects on the environment and human health. Its emissions contain sulfur combines with air to create the poison gas sulfur oxide. When this gas releases into the atmosphere, it causes polluting rain. Extracting coal from mines further damages soil and water resources, adding to the

Crown Capital Eco Management - ELECTRICITY: Natural gas, renewable energy will power t... - 2 views

  •  
    The path to low-carbon electricity generation in Texas will likely require the co-development and integration of both natural gas and renewable energy resources like wind and solar power, a new research report commissioned by the Texas Clean Energy Coalition has found. The white paper, prepared by the Brattle Group for the Austin-based nonprofit, states that despite perceived competition between natural gas and renewable energy resources in Texas, the reality is the two sectors can aid each other's growth and can eventually help Texas meet rising energy demand in an era of tighter environmental controls. "Low-priced natural gas and clean renewable resources are complementary, not competing, resources to displace other fuels over the long term. Coordinated development of both will lead to a win-win for Texas and the environment," Kip Averitt, chairman of the Texas Clean Energy Coalition, said in a statement announcing the results of the Brattle Group analysis. The report examined conditions across the Electric Reliability Council of Texas (ERCOT) territory, which has some of the nation's greatest wind power capacity and has undergone an unprecedented boom in natural gas production aided by hydraulic fracturing. Some have asserted that an abundance of inexpensive natural gas will displace renewable energy, thus keeping Texas from fully developing its extensive wind and solar resources. The Brattle analysis challenges that conclusion, asserting instead that "in the short run, low gas prices are extremely unlikely to change the fact that existing renewables will nearly always have priority over gas-fired plants since, due to the absence of fuel costs, their variable costs are lower than those of essentially all other resources." And longer term, the analysis finds, new gas-fired power plants may compete with wind and solar power, but such conditions will be predicated on fluctuation in coal and gas prices, shifts in federal and state energy and environmental poli

Climate change is happening 10 times faster than ever - 1 views

  •  
    Stanford University recently published a report in the journal Science pointing but the extent to which the climate change rate - so much heat absorbed in very little time -is overtaking any other eras of warming or cooling in the Earth's 65 million years history. If present estimates are precise, the researchers state, that pace will speed up to 50 or even 100 times quicker than anything we have observed in the past. Scientific American explains: They observed climate occurrences or primary transitions that have transpired on Earth from the time of the dinosaurs' extinction. Those include the time when the Earth came out of an ice age. Temperatures then went up between 3 and 5 degrees Celsius, similar to the amount scientists predict is possible with the prevailing climate change. But that change occurred within about 20,000 years, the scientists pointed out, and not mere decades as it is now the case. Another study conducted by University of Texas and put out in the journal Nature, has discovered that the Antarctic permafrost is also melting at a rate 10 times faster compared to anything measured previously, that is, in the last 11,000 years. The scientists explain that the dramatic shift is not due to higher temperatures but to altering weather patterns in which the region is experiencing more sunlight than before. The researchers of the Antarctic case are not overly worried at their findings, explaining that for the Arctic polar ice to melt at this rate would be much more problematic. The findings of the Stanford study are not as hopeful. To keep up with the present rate of global warming, says study author Christopher Field, we have to begin adjusting accordingly on a significantly faster timetable. The chances of reducing its effects now, in his calculation, is not so bright: To keep the temperature rise to about 1.5 degrees, the Earth would have to reduce its greenhouse gas emissions to zero by 2050, and then attain negative emissions, that is,

It is not Nuclear Power but Renewable Energy: the answer to climate change - 2 views

  •  
    There are a lot of people who assumes that the sole technology that is now available to substitute fossil fuels is nuclear power especially when climate scientists and some energy policy analysts take a "tough-minded" look at the numbers. Eduardo Porter of the New York Times made that argument last week when he wrote: …nuclear power remains the cheapest and most readily scalable of the alternative energy sources. There are many reasons why nuclear power is a bad solution to the climate crisis. The first reason is that the technology is not available. Nuclear power plants are capital-intensive, technologically complex to manage, and difficult, if not impossible, to site. These issues are not minor, investors chose putting their money somewhere else and communities are greatly against sitting a plant in their backyard. As a consequence, despite our knowledge on how to use electricity this way plus our years of experience practicing it, in the U.S. these plants will never be built in enough amount to reduce global warming. There is a slight difference between the technology of nuclear power generation and the technology of nuclear bomb development. It is now hard to put things back the way it used to be, let us admit that human political systems or organizational processes cannot manage the risks of this technology. Other issues associated with current nuclear technologies that cause them to become problematic. For instance, the toxicity of its fuel and waste should not be ignored. Dangerous accidents are rare but once it happened, the impact is intense and long-lasting. It is hard to judge the danger posed by a poorly managed one while a well-managed plant poses little real danger. There is also a possibility of sabotage. Terrorists taking over a plant and threatening to plant accident could hold a city hostage. Electric utilities are natural monopolies that necessitate government regulation.

Crown Capital management environmental monitoring on How Climate Change Is Worsening Ca... - 3 views

    Leading Scientists Explain: http://crowncapitalmngt.com/ Scientists have long predicted that climate change would bring on ever-worsening droughts, especially in semi-arid regions like the U.S. Southwest. As climatologist James Hansen, who co-authored one of the earliest studies on this subject back in 1990, told me this week, "Increasingly intense droughts in California, all of the Southwest, and even into the Midwest have everything to do with human-made climate change." Why does it matter if climate change is playing a role in the Western drought? As one top researcher on the climate-drought link reconfirmed with me this week, "The U.S. may never again return to the relatively wet conditions experienced from 1977 to 1999." If his and other projections are correct, then there may be no greater tasks facing humanity than 1) working to slash carbon pollution and avoid the worst climate impact scenarios and 2) figuring out how to feed nine billion people by mid-century in a Dust-Bowl-ifying world. Remarkably, climate scientists specifically predicted a decade ago that Arctic ice loss would bring on worse droughts in the West, especially California. As it turns out, Arctic ice loss has been much faster than the researchers - and indeed all climate modelers - expected. And, of course, California is now in the death-grip of a brutal, record-breaking drought, driven by the very change in the jet stream that scientists had anticipated. Is this just an amazing coincidence - or were the scientists right? And what would that mean for the future? Building on my post from last summer, I talked to the lead researcher and several other of the world's leading climatologists and drought experts. First, a little background. Climate change makes Western droughts longer and stronger and more frequent in several ways, as I discussed in my 2011 literature review in the journal Nature: Precipitation patterns are expected to shift, expanding the dry subtropics.

Fewer resources, greater stress, more disasters: Climate change linked to violence amon... - 1 views

  •  
    A world becoming warmer and experiencing more droughts and other climate-connected disasters is apt to bring about a considerable upsurge in fierce conflicts between individuals as well as whole societies, a major study has revealed.An analysis of 61 in-depth cases of violence has shown that personal clashes and wider civil conflicts grow considerably in number with significant changes to weather patterns, such as rising temperature and lack of rain, scientists said.Even fairly modest shifts away from the average lead to noticeable rise in the occurrence of violence, according to the study which theorized that the expected rise of in average world temperatures this century could result in a 50 per cent growth in major violent conflicts such as civil wars. The scientists suggest that climate shifts, especially rising temperatures, are bound to cause more frequent conflicts over progressively declining natural resources, on top of the physiological impact on people due to hotter weather. "We need to be cautious here. We do not mean that it is inevitable that further warming in the future will produce more conflict. We are saying that previous changes in climate -- especially, past temperature increase -- are connected with increasing personal and group disputes," said Marshall Burke of the University of California, Berkeley. "It is certainly possible that future communities will be more able to deal with severe temperatures than we do today; but we believe that it is risky to just presume that this will be so," said Mr. Burke, one of the authors of the study published in the journal Science. The study was based on an investigation of the scholastic literature for historical narratives of violent disputes, from individual aggression, such as murder and assaults to greater conflicts such as riots, racial tensions, civil war and even primary declines of civilisations that existed thousands of years back. Disputes between groups rather than between persons exhibited

Working towards Alternative Energy - 1 views

  •  
    Advocates of alternative energy have sustained that on a global rate, increasing energy consumption is connected to the renewed hostile extraction of natural resources from Africa to reach the target increasing demand in North America, Europe and the BRICS countries namely: Brazil, Russia, India, China and South Africa. They compete that despite of the growing demand for energy, more than 1.6 billion people has no electricity and about 2.4 rely only on fuel wood. According to the Executive Director, ERA/FoEN, Dr. Godwin Ojo, the event was conceived to deepen understanding of energy issues. It is the effort to find substitute to this irregularity that the Environmental Rights Action/Friends of the Earth Nigeria (ERA/FoEN) working in concert with over 50 civil societies, community groups and energy experts organized the Africa Alternative Energy Transition forum recently. Ojo said the event that attracted participants from across Africa was organised to coincide with the Global Month of Action on Energy by a coalition of Friends of the Earth, Greenpeace, Actionaid, International Rivers, 350.org, and some other international Non-governmental Organisations (NGOs) to reclaim power by resisting dirty and harmful energy and affirming the need for transition from fossil fuels to renewable sources of energy. He said in Nigeria, about 70 percent of the population depend solely on fuel wood for energy, a development, which has put the country in the ranking of the countries with the highest deforestation rate. He stated that the country is said to be losing 3.5 percent of her forest annually. "The rising energy demand is also leading to violent resource conflicts at the site of extraction. The energy expansions to dirty energy frontiers and technologies such as coal, shale gas fracking, or energy from biofuels have deleterious consequences on farmers and fragile ecosystems. "It is also important to note that the newly released Intergovernmental Panel on C

    * Body Heat Body heat can warm an entire building, complete with offices, apartments and shops. In fact, Jernhuset, a state owned property Administration Company is putting together a plan to capture body heat from train commuters traveling through Stockholm's Central Station. The idea is that the heat will warm water running through pipes, which will then be pumped through the building's ventilation system. While in Paris Habitat, owner of a low-income housing project in Paris, will use body heat to warm 17 apartments in a building as well. The said housing project is directly above a metro station near Pompidou Center. * Sugar Currently, researchers and chemists at Virginia Tech are developing a means to convert sugar into hydrogen. In which can be used in a fuel cell, and in turn it will provide a cheaper, cleaner, pollutant-free and odorless drive. The scientists combine plant sugars, water and 13 powerful enzymes in a reactor, converting the concoction into hydrogen and trace amounts of carbon dioxide. The hydrogen could be captured and pumped through a fuel cell to produce energy. Their process will translate into cost savings; it delivers three times more hydrogen than traditional methods. * Solar Wind This is way more powerful than humility currently needs is available right now, out in space. A stream of energized, charged particles flowing outward from the sun is actually from the solar wind. Brooks Harrop, a physicist at Washington State University in Pullman and Dirk Schulze-Makuch of Washington State's School of Earth and Environmental Science, think they can capture these particles with a satellite that orbits the sun the same distance Earth does. * Feces and Urine Feces contain methane, a colorless, odorless gas that could be used in the same way as natural gas. Human waste is also good and so is urine. * Vibrations Club Watt in Rotterdam, Netherlands is using floor vibrations from people walking and dancing to power its ligh

The variety of life on Earth, its biological diversity, is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. In some way or form, almost all cultures have recognized the importance of nature and its biological diversity for their societies and have therefore understood the need to maintain it. Yet, power, greed and politics have affected the precarious balance. Read "Biodiversity" to learn more. Why Is Biodiversity Important? Who Cares? Last updated Wednesday, April 06, 2011. Why is Biodiversity important? Does it really matter if there aren't so many species? Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, a larger number of plant species means a greater variety of crops; greater species diversity ensures natural sustainability for all life forms; and healthy ecosystems can better withstand and recover from a variety of disasters.

Crown Eco Management Human Thirst Makes Earth Quake | Crown Eco Management - 0 views

    As we all know earthquake is a catastrophic natural disaster. Most earthquake-related deaths are caused by the collapse of structures and the construction practices play a tremendous role in the death toll of an earthquake. In southern Italy in 1909 more than 100,000 people perished in an earthquake that struck the region. Almost half of the people living in the region of Messina were killed due to the easily collapsible structures that dominated the villages of the region. Though there are some ways to prevent this from happening, it can never be considered as risk avoidance. A larger earthquake that struck San Francisco three years earlier had killed fewer people (about 700) because building construction practices were different type (predominantly wood). Survival rates in the San Francisco earthquake was about 98%, that in the Messina earthquake was between 33% and 45%) (Zebrowski, 1997). Even a moderate rupture beneath a city with structures unprepared for shaking can produce tens of thousands of casualties. Due to this fact, Crown Eco Management determined that safety measures for this could not be compared to fraud prevention. Although probably the most important that we should know, direct shaking effects are not the only hazard associated with earthquakes, other effects such as landslides, liquefaction, and tsunamis have also played important part in destruction produced by earthquakes. According to the Crown researchers, some earthquakes are not natural. Human beings can actually cause them. That's the case with an earthquake in Lorca, Spain, last May. The quake measured 5.1 on the Richter scale and killed nine people. According to an analysis published in Crown Eco Management, the Lorca quake was caused by the extraction of groundwater from an aquifer near the fault that slipped. In circumstance, it does not take much to trigger an earthquake. Oil and gas wells, rock quarries, even the added pressure of a reservoir lake behind a new dam can cause

Watch 60 Years Of Climate Change In 15 Seconds - 3 views

  •  
    source: http://blog.crowncapitalmngt.com/watch-60-years-of-climate-change-in-15-seconds/ According to NASA, 2013 was tied (with 2009 and 2006) for seventh warmest year globally on record, dating back to 1880. NASA scientists have played a leading role in climate research in recent decades and the agency's Goddard Institute for Space Studies (GISS) this month updated a report analyzing worldwide surface temperatures. "Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change," GISS climatologist Gavin Schmidt said. "While one year or one season can be affected by random weather events, this analysis shows the necessity for continued, long-term monitoring." The NASA data finds that with the exception of 1998, the 10 warmest years in the 134-year record have all come since the latest turn of the century, with 2010 and 2005 ranking as the warmest years on record. cliamte Global average temperatures for 2013 (Credit: NASA) To drive the point home, GISS created the below animation that shows the increase in temperatures worldwide over the past 60 years, compiled from data collected by over 1,000 meteorological stations around the globe. A release from NASA makes the case that the increase in temperatures over the long-term is more a social problem than a matter of eons-long natural climate patterns: Driven by increasing man-made emissions, the level of carbon dioxide in Earth's atmosphere presently is higher than at any time in the last 800,000 years. This summer, NASA plans to launch the Orbiting Carbon Observatory with the goal of studying both natural and manmade sources of carbon dioxide, one of the gases believed to be largely to blame for climate change.

Reason why is Twitter's IPO so unusual | Crown Eco Management - 1 views

  •  
    TWITTER came up with a business that allows people send out information quickly. The micro-blogging service sent out just one tweet on September 12th informing the world it had filed the required IPO papers confidentially with America's Securities and Exchange Commission (SEC) when it came to its initial public offering (IPO) but then there was silence. Normally it is mandatory to all companies to publish information regarding them right after they have submitted their initial IPO documents to the SEC. However Twitter took benefit from provision in America's Jumpstart Our Business Start-ups Act-or JOBS Act for short-that permits "emerging growth companies" to kick off the IPO process confidentially. They should be able to publish the IPO earlier than three weeks before they proceed on investor road shows to advertize shares. The act characterizes promising growth firms as ones with less than $1 billion of yearly revenue. The JOBS Act became law in April 2012. It is by giving some companies the option of filing for an IPO in secret that aims to encourage more flotation. According to the SEC, by the end of June 2013 roughly 250 companies in America had filed IPO documents confidentially. For many reason this approach appeals to Twitter. The firm anticipates that by maintaining its financial performance confidential for a while, and then heading fast to a listing, it can keep away from the kind of hype that surrounded Facebook's IPO in 2012. Although Twitter must reveal its correspondence with the regulator when it finally publishes its IPO documents it can also address any concerns the SEC has about its submission in private. It is hopeful to shun the fortune of Groupon, which exposed particulars of its finances immediately after it filed for an IPO in 2011. Several of the firm's accounting rules were openly questioned by the SEC, which frightened investors. There are other advantages too. If it wishes to, Twitter must only publish two years of audited f
