battery energy storage system The Renewable Energy Revolution: What's Going On?

by:MERITSUN     2019-06-30
One drawback of today's information society is that so much information is purely rough, perhaps flashy, and attention --Acquired by design, but ultimately worthless for any useful purpose.[Insert the latest celebrity gossip story here and ask yourself how many people will remember it in a year, or in some cases even remember its theme.On the other hand, information that really helps inform public policy is still not available, or at least ambiguous.
It is often covered up by false information, inaccurate rumors and outdated facts.Today, the status of renewable energy is a good example.This is a positive area of policy.For example, the EU has just set a new carbon emissions policy, including a unified goal for renewable energy.
Is the agreement a viable compromise to continue Europe's leadership in cutting carbon emissions, or is it simply swinging in the face of a long economic crisis?Or consider the American incident.Last year, Georgia in the United States has so far been less friendly to renewable energy, and although it has quite good potential solar resources, it has taken an interesting step.The strange coalition of bed friends between the eco-activists and the state tea party quickly became known as the "green tea alliance", successfully lobbying the Public Service Council to force the state's dominant power company, South Georgia, buy 525 MW of solar energy.
The green tea alliance is also reported to be active in some other Southern states.Is it possible that their efforts will benefit the public by reducing emissions and increasing competition for electricity supply, or simply hurting consumers by raising electricity prices?In the news, a mysterious right wingIn the past, the Yongan group, which was fully funded by Exxon petroleum and Kohe brothers, will certainly push forward the latter idea.S. legislative exchange commission seeks to weaken national renewable energy standards, characterized by power gridsConnect home solar owners as "free passengers" and try to punish them.
Is there any merit in this argument, or is this simpleAn organization that clearly works for the common good is actually defending vested interests?We can also consider wind energy, not solar energy., 2014.It has been around for 20 years, but has been attacked by political allies in the interests of fossil fuels, such as the prosperity of the United States.(Apparently, the only good energy subsidy for them is fossil fuel subsidies.
Predictably, the American Wind Energy Association is lobbying to restore tax credits, as are citizens and groups concerned about climate change.In 2013, the installed capacity of wind power in the United States exceeded 60 gigawatts.(Start at 2.5 giva, 2000.) Wind power is now reported to provide more than 4% of the electricity, at a cost comparable to coal.
AWEA believes that this progress in clean power generation should be further expanded and supported.Congress provides credit to further encourage the rapid development of wind power?Cut subsidies for fossil fuels and provide a level playing field?Introducing a carbon tax, which will explain the hidden costs of using fossil fuels, thereby balancing the competitive environment of energy in different ways?Renewable energy and nuclear power accounted for 57% of new capacity in 2013, while fossil fuels accounted for only 43%.Energy policy experts will note that the nameplate capacity is not equal to the actual power generation as wind and solar energy are not continuously available.
(On the other hand, once the wind or solar power capacity is built, it will be used whenever it is available, which is called the "value order effect ".But usually, the capacity map is available first.kilowatt mark.It's easy to see how good this clean energy effort is for China: her notorious air pollution is not just a national grievance, but what other countries are asking for clean air tourism?This is a major drag on the economy.
(According to a recent study by the Massachusetts Institute of Technology, the cost in 2005 reached an astonishing $112 billion.) Improving air and water quality will bring benefits in public health and economic productivity.In addition, China's domestic use of renewable energy supports and complements her efforts to become a world leader in the manufacturing of clean energy equipment, from solar panels to wind turbines and so on.
This is an astonishing push for Chinese companies to dramatically increase production so much that the problem of oversupply, especially solar panels, challenges manufacturers around the world to adapt to survival quickly enough.Many failed solindera are the best.Especially in the United States.However, although early casualties mainly occurred in developed countries, Chinese manufacturers are also feeling pain today.Wuxi Suntech, the main unit of the world-Wuxi SuntechSuntech, the leading panel maker, was forced into bankruptcy in 2013 as more bankruptcies, acquisitions and mergers are expected as the industry integrates.
Therefore, expanding the domestic market for renewable energy can be seen as a strategy to protect China's manufacturing capacity in the industry.As some may claim, is this a cynical window dress, or is it a socialist "bubble" that will certainly pop soon "?Or will this drive the global environment for renewable energy in the coming decades?The story mentioned is only an option, but at least enough to show the scope and speed of energy change in the world today.What is lacking is a reliable synthesis of all this data, which allows us to clearly predict the development of renewable energy in the coming decades.
Find interesting websites and usually have obvious views.cleantechnica.com.It covers all renewable energy.From electric vehicles to climate change to energy policy and politics.It is also explicitly set as a booster for renewable energy, so you have to read its article in your mind, you can rely on clean technica to present the case of renewable energy in an engaging and persuasive way, but it does not pretend to be objective or remain calm.
(Of course, that doesn't mean it's wrong.
The climate is hot.
com.
It focuses more on policy than on clean technology and tends to be more technical, especially in discussion forums.However, it is very skeptical about renewable energy (often criticizing its costs, or allegedly undervaluing them) and is very supportive of nuclear energy.Again, it is valuable to articulate opinions and ask good questions, but not necessarily without prejudice.
IRENA should not be ignored as a source of information.It is an independent international body established in 2009 with the goal of promoting renewable energy.(So, again, we have a source with a clear position on the topic.
But their analysis seems to be serious and there should be some credibility.Another advantage of the IRENA report is that Member States--More than 160 countries are joining-A real global vision.The rise of renewable energy in the developing worldappreciated;Reading IRENA's website will soon make this clear.
To find a replacement for the Internet, I recently turned to the local library and got three titles.I will discuss them briefly in turn.Renewable energy: the worldThe changing power of alternative energy.Renewable energy: the worldThe changing power of alternative energy.
Jeremy Shere.
San Martin Press, New York, 2013.
First Mr.
Shereâx80x99s book.
Compared to ordinary people, I am fairly aware of the latest trends and progress in renewable energy...I still have a rough idea of where and how the energy we consume at home and on the road is generated...I don't have a clear understanding of the big picture, and the knowledge of the dozens of alternative energy technologies we hear every day really adds something new and viable.
I have almost no idea how these technologies will have a real impact on our lives in the near future., and long-term future.Until, that is, buy a new car and negotiate countless energy sources --The relevant choices in the game make people realize that renewable energy is no longer something in science fiction.Now, it's slowly but surely changing the world in a big, small way.
Sounds like me.
Maybe he's looking for a better picture that will give the rest of us an answer?But as I went deep into the introduction and found out about his life scene in 2075, my hopes were soon dashed again.Although inferred from the current reality, it feels like an update to the world public service short film 1950 s tomorrow: readers are invited to imagine a home with solar panels and wind turbines on the roof, not to mention a biofuel system that powers one of your cars, brew ethanol from waste automatically collected from your family's food residue...Gee whiz!But this book has considerable advantages.
First of all, it provides a useful historical context for technologies that we often (wrongly) think have emerged --century.As Mr.Shere commented that renewable energy is a less important topichistoricized.For example, who knows that Henry Ford took Thomas Edison on a trip to Florida in 1917 to find land for biofuel production?Or a "hithitss" at 1878 Paris Expo is a concentrated solar steam engine that can (and does) pump 500 gallons of water per hour, or, connected to the right freezer, ice with water and sunlight?It's dark and very loud (we had to put on earplugs) and it's hot (especially if you're standing anywhere near the boiler, inside the boiler, A huge fireball is about 2,000 degrees Fahrenheit and sexy.
Walking down the stairwell, I instinctively grabbed the railing and my hands were covered with a thin layer of dust.There are pipes, large boilers, various generators and machines running at full capacity 24 hours a day.of the thing.Shere covers renewable energy in a fairly comprehensive way, including biofuels, solar, wind, geothermal and various types of Hydro (starting today)The Edge machine draws electricity from water flow, waves, or tides to attract a plot around the birth of commercial electricity in North America, as George Westinghouse, Thomas Edison and Nikola Tesla (among other things) It is fascinating, vivid and easy to read.
However, for me at least, this is not entirely satisfactory, ending with a "fence" to some extent --The way to sit.Even given how far renewable energy technology has gone, if they are going to really compete with fossil fuels, they still have a long, hard way to go and it still supplies the vast majority of the world's electricity.It is certain that traditional energy companies will do everything they can to ensure that fossil fuels will continue to dominate at least in the coming decades, if not longer.
...Ready to claim with confidence that in this civilization, renewable energy occupies the largest share, which is not only possible, but also necessary and inevitable.Even thirty years ago, such a statement was absurd.But it is becoming more and more realistic today.
Once, the main obstacle is technology.
Today, while technical challenges remain, the toughest obstacle is the political one...But maybe it's unfair to criticize Shere's fence.Still, if there is uncertainty about the future of renewable energy, can we really expect SirDo you disperse it alone?Renewable energy: Opposing viewsRenewable energy: Opposing viewsDavid M.
And Susan Masser.
Greenhaven Publishing House, Mount Farmington, Michigan, 2012.If the comment last quoted by Shere sounds like an objection, then this is a proper threadAn anthology of David Hogan and Susan Masser.Their book is part of a series of opposing views on various different issues.
The assumption is that taking into account the view against the point of view will foster critical thinking and a deeper understanding, not just a spoon --Pre-feed readersConclusion of digestion.It may indeed be a good idea.But execution is important and I find the implementation of this concept disappointing.This book itself published in 2012 article itself often few years old â x80 "the first Greenpeace organization of article was for â x80 x9c Renewable energy and climate change, it was first launched in 2007.
For example, Jason Harrow's 2011 article, reproduced on the Harvard Law and Policy Review blog, argues that climate change should not do anything because nothing can be done now;Renewable energy is too expensive to be cheaper soon.Actions may cost work, and in addition, the moral hazard that we may fool ourselves is that ineffective actions are sufficient to delay or block effective actions.However, according to the Alliance of relevant scientists, project data from the United StatesS.
average U.
S.
.According to a report from the solar industry association.âx80x9d(Mr.Harrow did not provide any support for his opposite statement.In fact, this is a common mistake in many books: there is rhetoric, there are assertions, but there is very little analysis.
In fact, the first article that seems to have done a reasonable job in this regard is the seventh (!) In this book, a 2011 article written by Amory Lovins, originally called The Myth of the footprint of renewable energy, completely reveals the idea that renewable energy requires a huge footprint of land.In other cases, the analysis is there, but it is broken by what seems to be the agenda.For example, an article from the 2010 Heritage Foundation Center, originally the renewable energy standard: the price Americans really need to pay, compares the costs of various energy sources and thus damages renewable energy sources.
However, it does not take into account at all any known external costs of "cheap energy" coal, and basically does not take into account the cost trends discussed above.The former is a bigger problem than most people realize: The 2011 economic analysis of Nicholas Mueller and others found that the range of damage related to coal and electricity ranged from 0.8 to 5.6 times the value added.Perhaps most disturbing, however, is the disconnect between grandiose statements and their actual foundations.
For example, the article claims that, among other bad things, renewable energy standards, as outlined below, cut the national income of a family of four by $2,400 a year, reducing more than 1,000,000 jobs.Unfortunately, it is not possible to begin to understand the basis of this article as appears in the anthology, as the outline of commitment for the analyzed RES does not appear "belowo" (or anywhere else in this volume ).) The only hint provided is a sidebar diagram that takes into account the cost of providing 100% of the electricity [home.
Nevertheless, the anthology is not worthless.It does provide a window for various schools of thought in the renewable energy debate.For example, an article by an Australian Ted Trainer, an article of 2007, originally titled "renewable energy: an unsolvable consumer society ".
I find it not convincing in the end in several ways, but it is a good example of a school of thought, usually associated with a movement commonly referred to as an "ecological movement"Socialism, it believes that our energy is not technically fixed.Related environmental issues are possible.Mr.For example, the trainer advocates and works on a simpler way that involves more democracy and less technology.
As the introduction to his article says: "The only answer suggested by the coach is to dismantle the consumer --The development agenda of capitalism, creating smaller communitiesA sustainable lifestyle.For me, this is part of the problem, based on his analysis, and it seems to be out of a desire to criticize renewable energy, just like a desire to criticize the threat of renewable energy to pure capitalist free markets.Another problem is that his solutions, although you have to look for them outside the scope of the current anthology, in which they are just implied and seem too utopian to be credible.
The hard physical limitations of growth are clearly the time for us to start responding to the effects of zero growth.Economic growth in energy.For example, Sir.60 times it is now!(Focus on the original text of the train.) The three points are a bit optimistic if this is the right word compared to long-longLong-term growth, but not so.
.) But a 60-The doubling of global economic output is a thought-provoking prospect, sufficient to make the assessment of at least trainers controversial, that is, there is no credible assumption in terms of technological progress, energy conservation, etc.It can be proved that the problem can be solved...This is something that others like Mark Lynas echo.
Another ideaControversial is the article by Charles Falberg, a nuclear engineer at MIT, who believes that by working with renewable energy, nuclear energy can help ensure lowcarbon future...Advocates of nuclear power, such as doctors, are too frequent.Forsberg) and advocates of renewable energy were given another low-The carbon industry seems to be a zero replacement for fossil fuelssum game.
This kind of attack seems a bit pointless, because in any case we will all have nuclear power plants and increase the deployment of renewable energy in the next few decades.The idea of Falberg is worth considering.If these two technologiesIn the lives of future generations, is there a potential synergy that can increase the utility of these two technologies for society?When the wind or solar energy is insufficient, when the wind or solar energy is abundant, the nuclear power plant will support the wind and solar energy. On the contrary, the energy of the nuclear power plant will be used to produce biofuels and/or hydrogen, Forsberg said.
Although its practicality is still unknown, it is conceptually elegant.As shown by the examples discussed above, the anthology of Nguyen and Moussa may be flawed, but it may be of great interest to some readers.In the end, it does achieve, at least to a certain extent, the editorial purpose that triggered thought-provoking.
Owner's energy Manual: your off-grid guide.Owner energy Manual: your off-grid guide.Paul Scheckel.Story Press, North Adams, Massachusetts, 2013.I approached the last of the three books, the homeowner energy manual by Paul shekel, with the lowest expectations.
Its subtitle is "your off-the-net guide" and its cover movement has four main points, starting with "build your own bike"Generator and solar collector.There is nothing wrong with amateur projects in the renewable energy sector, but this commitment seems to be more gimmicky than I would like.But, of course, it is notoriously unwise to judge a book by its cover.
Amateur projects do exist, but you won't be exposed to them until you finish half of the book completely.The first half was very practical, providing reliable information on how to make your home renewable by improving energy efficiency.Mr.Scheckel is a certified energy auditor and consultant whose discussion in this part of the book is a model of the practicality of nuts and bolts.
The second half was part of its commitment to become an amateur Handbook.But it's also more enlightening and easier fun than I thought.For example, about MicroThe hydro project resulted in several very pleasant times dedicated to calculating the potential of hydro somewhere I know in rural South Carolina.
Initially very exciting, it seems that you can potentially use the hydro system as a reasonable backup of the solar PV system.Then I found the decimal point.Oh, well.However, even if the power of the Assumption is barely so, the work is instructive.You can save money with other items like biogas manufacturing, but don't use it if you consider the value of your time.
So if you like to do these projects, then these projects are very meaningfulpositive?But it's unlikely to add as much financial value to your family as it does for a second job.In contrast, solar hot water and photovoltaic (PV) can be cost-Valid according to the conditions on your website.In a hypothetical (but realistic) example given by Scheckel, the solar photovoltaic system is almost balanced in its life cycle, with a growth rate of 2%.
(Finally, after inflation, it is assumed that electricity costs are up 2% per year.) Does not include potential savings due to incentives, lower installation costs or higher energy prices.In our families, we take our future families and their energy use and carbon footprint very seriously.
Ironically, based on my initial response, the book Scheckel ended up being the one we might actually buy.The exploration of reliable information on renewable energy, reducing carbon emissions and the future of our energy economy is still underway.The information I found does not provide reliable answers about the future of the renewables society.
It is clear that there are broad prospects for renewable energy.Moreover, it is now clear that the whole society has made great progress in achieving this commitment in practice;In recent years, the use of renewable energy has shifted the industry from experimental to industrial.However, in the context of the renewable energy revolution, we still have a long way to go to solve the carbon problem.
To do this, the deployment rate needs to be continuously improved over the next period of time.Unfortunately, it is not clear if this will happen.In this regard, the decline in costs may reach a critical point.
(In fact, some people think this has happened.) But that's not sure yet, and there are some signs of a political backlash that there is less support for incentives to use renewable energy.What could be this slow growth?We do not yet know how renewable energy will change the energy business.
Germany's energy conversion is the leading experiment in the world today, and it is indeed a chaotic and complex experiment.Germany's experience clearly shows that renewable energy can provide a large part of the total power generation without disrupting the stability of the grid, in fact, this is much larger than what was considered possible a few years agoBut business and governance issues seem far from a stable, mature solution.As a result, today's renewable energy has raised concerns in terms of technology, finance and politics.
Although these questions can certainly be answered over time, human civilization does not have enough time to solve our carbon dilemma.(See my center, "Climate change: how much time do we have?\ "The link is at the bottom right.Lingering concerns about renewable energy will certainly continue to spark heated debate among those who believe that renewable energy is a solution in the near future;Nuclear energy is the solution to the problem;The solution to the problem is to improve energy efficiency;Economic tightening is the solution to the problem;Or a realistic solution involves all of the above.
Some people would even argue that there is no solution, we are all doomsday people. I think they prefer to argue over alcohol as a pain killer.) Against the point of view, in fact!Nevertheless, renewable energy also continues to provide great hope and excitement for a new, more sustainable energy economy and reflect what has been achieved in achieving the urgent goal of reducing carbon emissionsThe Enterprise, vision, persistence and ingenuity of many ongoing projects in the renewable energy sector have shown several of them in this center ---It is extraordinary in oneself.
The story of renewable energy is much faster than it can write.But if the results don't count on that much, it must be fun to try to keep more fun.Update 10/17/2014--The International Energy Agency, the primary source of information and analysis on world energy use, recently released a report documenting the development of solar PV by the end of 2013.
China is an incredible leader in installing solar PV.920 giva was installed in 2013 alone.This overshadows the previous one.A nine-year record.305 GW, set by Italy in 2011.Germany, no longer the leader in photovoltaic installation, only 3.Nevertheless, an increase of 305 in 2013 retained ownership of most installed capacity, accounting for 25% of the world's total installed capacity.
Next is China, 14%.
By the end of 2013, the global production capacity was 140 GW, and China's target was 10-The new 14gw this year, China is likely to surpass Germany in 2015.The region with the highest share of solar photovoltaic power consumption is Italy, which accounts for nearly 8% of its total power generation.Strong growth in Asia and the United States has significantly reduced Europe's leading position in solar photovoltaic power generation capabilities.
The technology is clearly global.
Growth continues along the path of roughly exponential growth.No-It is known how long this will last, but some analysis suggests that 500 GW may continue by 2020.(See the picture below.According to preliminary data from industry research firm GTM, global solar power generation reached 256 gigawatts in 2015.
-It is now expected to be close to 800 GW by 2020.2015 figures have increased by nearly 83% over the above 2013 capacity.Compared to the 2020 GW mentioned in the last update, the estimated capacity of 500 is also a bit amazing: at least 50% more.
Wind power continued to grow rapidly in 2014.Cleantechnica.51.In 2014, 2 GW of fresh air capacity was installed, setting a new annual total capacity record. By the end of the year, the cumulative installed capacity was as high as 372 GW.
Asia is now the continent with the largest cumulative capacity, with 37.3% of all wind power capacity, 1.The former European leaders accounted for 23 of the above five percentage points.7% installed in 2014.New facilities have tripled in Brazil.In 2014, when leaders saw 23 GW installed in China.
3 GW, 5 for Germany.
1 GW and 4 in the United States.
9 GW.
This is more than the world's capacity increase in 2004.Capacity growth in Asia is also significant, especially given China's position as a major greenhouse gas emitter.Obviously, those who greeted us last yearChina's climate change agreement says China will not act immediately, which is completely out of touch with reality ---Of the world's 45% wind power, China's new wind power accounted for more than 2014.
According to the Global Wind Energy Council, 2014 new projects have been added, bringing the global cumulative capacity to 396.5 Gigawatts.In terms of the environment, the world power generation capacity of all sources is about 5,000 gigawatts, so at some point in the next few years, wind energy should account for more than 10% of the global power generation capacity.In 2015, the capacity of wind and solar power was expanded again.
Total installation and power grid in China-It is reported that the connection capacity has reached nearly 130 gigawatts, while the total solar capacity has exceeded 50 gigawatts.In terms of wind power, transmission capacity is still a problem, and nearly 15% of wind power is wasted ("reduced") due to insufficient transmission capacity ").(The good news is that coal and electricity have been cut even more because of slowing economic growth and improving energy efficiency and slowing electricity demand growth.
Fresh air developments in the most restricted northern provinces have been put on hold, although China as a whole is expected to add 20 gigawatts of wind in 2016.In the United States, wind capacity increased by 13% to 74 installed capacity.47 GW, including nearly 18 GW in Texas.For solar, more than doubled in proportion, more than 26%--In absolute terms, an increase of 7.
26 GW, a total of 27 installed units.
4 GW.
It is expected to double in 2016.
Globally, renewable energy capacity has increased by more than 8% and solar capacity has increased by 26%.The total increase was 152 GW, and the cumulative installed capacity was close to 2,000 GW, which was 1,985 GW.(It is almost certain that the installed capacity has exceeded the milestone of 2000 GW since it went public in 2016 ---However, it will take time for this data to be entered.
Another renewable energy milestone has arrived, according to clean technica-This is the product of the Australian market.It is reported that the cost of renewable energy and battery storage is now equivalent to, or actually, the cost of the most economical "peak" power form before, used to compensate for sudden changes in power grid demand or power generation ---natural gas.Although the price of natural gas in the United States is cheap due to the fracking revolution, it is still a very important milestone in the renewable energy revolution.
