我很高兴最近在摩洛哥出现了许多太阳能板,不过对于这个整年都日照充足的地方来说数量还是太少了

The amount of solar power added worldwide soared by some 50% last year because of a sun rush in the US and China new figures show.

新的数据显示,去年全球太阳能发电增量提高了50%,主要原因是在于美、中两国的推动。

全球太阳能增长50%

New solar photovoltaic capacity installed in 2016 reached more than 76 gigawatts a dramatic increase on the 50GW installed the year before. China and the US led the surge with both countries almost doubling the amount of solar they added in 2015 according to data compiled by Europe’s solar power trade body.

2016年,全球新增太阳能光伏发电装机量超过了76GW(十亿瓦特);同去年的50GW增量相比,有了大幅提高。欧洲太阳能贸易机构的统计数字表明,中国和美国在2016年的太阳能光伏发电增量是2015年光伏发电增量的2倍,远远领先其他国家。

Globally there is now 305GW of solar power capacity up from around 50GW in 2010 and virtually nothing at the turn of the millennium.

目前,全球的太阳能发电装机总量达到了305GW,2010年时则为50GW,而2000年时则几乎为零.

Why the countries of North Africa and the Middle East aren't harnessing this clean resource big-time I don't understand. Ever been to Israel?

Britain is ahead of Spain because Spain has a huge investment in wind which has been a more established alternative for a long time and which the hobbits in Britain don't like because it spoils the view and "kills little birds" (they say while downing their bacon and beans). Also as you saw Solar is a tiny investment compared to the overall portfolio so at those levels it's easy to be ahead.

我不理解,为什么北非和中东国家不利用这些清洁能源呢?去过以色列吗?
Nete 75
英国领先西班牙,这是因为西班牙已经在风能发电中投入了巨额资金,长久以来风能发电是一项更成熟的替代能源。英国的霍比特人(译者注:应该是讽刺)不喜欢风能发电,他们认为风能发电会影响风景、杀死小鸟(他们在说这话的同时吃着培根就着豆子)。如你所见,和总的投资组合相比,光伏发电的投资规模很小,所以这也解释了容易领先的原因。

But the powerwall2 retails for ?6k. 

但是这个能量板要六千块?

I reckon the dude was standing on a panel to get the shot. Agree nice shot and love the green bag against the blue of the panel. 

我认为这男的站在那板上是为了拍照。很好看的照片,喜欢绿色宝宝放在蓝色板子上的感觉。

Tidal power is not costfree any more than any other form of renewable. It impacts the ecosystems it is placed in like any of the other means. The correct thing is to consider a varied portfolio with all the different technologies being made available where posible. Tidal is not THE solution but A solution one of several to wean ourselves first of fossilfuel and then of constant and unnecessary energy use. 

潮汐能可不比其他可再生能源便宜。它也像别的发电方式一样影响所在地的生态。正确的做法是考虑采取多样组合让不同的技术发挥应有的作用。潮汐能无法完全解决问题,只是众多选择中的一项,可以让我们先是摆脱对化石燃料的依赖,然后再摆脱持续的不必要的能源使用。

Crazy that the subsidies were cut in 2016. 

疯了吧2016年砍掉补贴。

I am so optimistic about PV and wind. Mainly because the storage issue is about to be demonstrably solved. But also PV is behaving a little like the silicon processor chip which everyone knows doubles in power every two years. The price per electric output from PV is falling such that if you out for power / energy now by tender renewables always win. Think about that : even "nasty" deniers who are driven by sordid commerce will go for green ahead of coal/gas and Peat. Only wood- burning stoves to go! We need 1.57 times more acreage than those at the equator. to get the same yield As prices fall we can "over specify" as the trade would say. And begin to overcome our latitude problem. Add in storage and the picture becomes even better. So government subsidies conservative thinkers we are at the turning point inevitably on a good path. Rejoice.... 
Green-ness and economy both side of the grid which though it was built in a previous power station era will be used in this next wave. As to PV the Swiss have worked out how they can move to face the sun as it moves across the heavens and by using good slicing methods we can generate from increased parts of the spectrum. There is on nuclear power station protesters can't close and it can do it all for us : the Sun. Three months ago would never have said this! Enjoy the transformation. As I have. 

我对光伏电池和风能抱有乐观态度,因为能量存储问题肯定会解决的。同时光伏电池有点类似硅处理器芯片,所有人都知道每两年它们的处理能力翻倍(摩尔定律)。获得相同单位电力输出的光伏电池价格在下降,如果你想招标寻求动力/能源,可再生能源总是会赢。

想想看,甚至被肮脏的商业利益驱使的“恶劣”否定者相对于煤/石油和泥炭都会选择绿色能源。Only wood- burning stoves to go!假如要取代木柴火炉??我们需要现在赤道地区的1.57倍面积来铺设光伏电池来获得相同的能量收率。随着成本下降,商业上可以指定使用光伏电池。并且纬度问题已经在被攻克。加入存储问题,前景会更好。所以政府补贴和保守思想者都无可避免的转到一个好的方向上。祝贺。。。

尽管现有电网是在之前的电站时代建造的,其绿色性和经济性将在下一波发展中继续发挥作用。对于光伏电池,瑞士人已经研发出可以随太阳移动而运动的光伏电池,使之一直面朝太阳。而且使用更好的切片制造方法,光伏电池可以从更多的光谱中制造电能。有一个核电站反对者无法关闭的核电站并且它会一直为我们供能,那就是太阳。三个月前我都不会这么说!享受转变吧,就像我一样。

Since Jaguar-Landrover is Indian owned how can it be that any electric car technology it owns is British owned? I'm afraid that our domestic car industry is almost entirely foreign owned aside from minnows like Morgan. Even the stately Bristol is Indian owned now. 

由于捷豹路虎现在已经是印度所有,所以该公司所拥有的电动汽车技术怎么可能是英国的呢?恐怕我们国内的汽车产业几乎都卖给外国人了,除了像摩根这样的小公司。甚至是高贵的布里斯托飞机公司都卖给印度人了。

And yes solar panels might vary in output by 10% or so across their typical temperature range; this does not compensate for seasonality which is in the area of 100s of percent. Indeed. No doubt some hack will come along and say this is not a problem but if you take the datasets from pfbach (or some other site) you see immediately big issues even when correlating on an hourly basis. What you find is very weak correlations and this does not change much for winter and summer. What you will probably be told is they correlate "on average". The other problem with complementary power is that you are saying that you will not have capacity available. In other words for perfectly complementary sources when one is generating the other is not and vice versa. Now there can be some amount of overlap but think about it. If you have a capacity factor of one source at 30% and another source at 10% what likelihood for having compensating power sources for say 50% of their time? 

是的,太阳能板的输出在它们的常规温度区间中,不同温度可能会有10%左右的浮动,这没法在季节变化间补偿,这种情况浮动会达到100%。无疑,一些人会说这不是个问题,但是如果你分析下pfbach(或其他网站)的资料,你会立即发现这即使以小时为单位考察也是大问题。你会发现它们具有非常弱的相关性,无论是冬季还是夏季,你可能被告知它们“大体上”是相关的。另一个互补电力的问题是,你没有可用的功率。换句话说,对于理想的互补能源,当一个在发电,另一个没有,反之亦然。真实情况下可能会有一些重叠,但想想吧,如果你对一种能源有30%的利用率,另一种有10%,你这互补能源怎么能达到50%的使用时间?

I especially like how solar energy was collected by plants and then stored and concentrated for us in the form of oil gas and coal. How kind! You think that plants turn solar energy into oil gas and coal? 

“植物收集太阳能然后储存集中起来以石油天然气和煤炭的形式提供给我们。”真是天真!你真的觉得植物可以将太阳能转变成石油天然气和煤炭??



EnviroCapitalist
Because not all homes are suitable for solar panels and putting them on would increase the cost of the new home and make the affordability crisis worse. 

不是所有房屋都适合安装太阳能板,强行安装只会增加新房成本,从而导致买房难问题更加严重。

I hope that we China and the United Kingdom can cooperate in energy conservation.To achieve the purpose of mutual benefit。

我希望我们中国可以与英国在能源利用方面合作,实现双赢。

I checked my City on an air quality map the other day and it is 20% over safe EU limits The Tories have a plan to address that - take the UK out of the EU and hey presto our cities are no longer failing to meet EU targets for safe breathable air! All hail Brexit! 

我在空气质量地图上查了下我的城市,超出欧盟安全标准20%。但是保守党有办法解决这个问题,那就是脱欧,这样一来英国城市就不用去满足欧盟的空气指标了!脱欧万岁!

Yeah because it's other people giving you that money They are rewarded for investing their money in something that the nation needs. They could have used that cash on a new kitchen big holiday pissed it all up the wall - none of which would have benefitted you or I. Instead they locked it up in an investment that also benefits all of us and you complain. 

哈因为这些钱是别人用他们自己的钱去投资这个国家需要投资的项目而得到的奖励。他们大可以把这些钱用在大厨房、长假、花天酒地上-这些选择对你或我都毫无益处,然而他们并没有而是把这些钱套在一个造福所有人的项目上而你却在这儿抱怨?



scribespeak
In Morocco recently I was pleased to see some solar panels springing up but still woefully few for the huge amount of sunlight they get nearly all year round. Why the countries of North Africa and the Middle East aren't harnessing this clean resource big-time I don't understand. Is it because they're still wedded to oil? Or too busy in-fighting or what? 

我很高兴最近在摩洛哥出现了许多太阳能板,不过对于这个整年都日照充足的地方来说数量还是太少了。我不懂为什么像北非 中东这样的国家不去利用这种一流的清洁能源,只是因为他们还依赖石油还是苦陷于战争还是什么?
