Builders in California will be required to fit solar panels on most new homes from 2020 under new building standards adopted on Wednesday, a move that is the first in the United States and could provide a big boost to the solar industry.
The decision, adopted unanimously by the five-member California Energy Commission, is part of the state’s effort to fight global climate change. It came despite estimates it would raise the up-front cost of a new home by nearly US$10,000 in one of the most expensive parts of the country.
The Commission estimated the standards will add about US$40 to monthly mortgage payments but will compensate for that by saving residents US$80 a month on energy bills.

“We cannot let Californians be in homes that are essentially the residential equivalent of gas guzzlers,” Commissioner David Hochschild said ahead of the vote.
The new building codes include updates to building ventilation and lighting standards. They are collectively expected to reduce the state’s greenhouse gas emissions by 700,000 metric tons over three years, a level equal to taking 115,000 cars off the road, according to state officials.
The vote was a major win for the solar installation industry, which already counts California as its biggest market. Demand for solar equipment in California could rise by 10 percent to 15 percent because of the new standards, the Energy Commission forecast in a study earlier this year.
California has one of the most ambitious renewable energy mandates in the country, with a goal of sourcing half of its electricity needs from renewable sources by 2030. At the end of 2017, it had reached about 30 percent, according to the CEC.
Because of such policies, the most populous US state has frequently been at odds with President Donald Trump’s aggressive rollback of policies to combat climate change. Governor Jerry Brown is planning a global climate summit this September.
Just 9 percent of single-family detached homes in the state of 39.5 million people currently have solar panels, according to a 2017 US Department of Energy report the Energy Commission cited.
Buildings that are shaded or have a roof that is too small to accommodate panels will be among those exempt, California Energy Commission spokeswoman Amber Pasricha Beck said.

美國加州上週三通過新的建築標準,自二O二O年起,建築商必須在多數新建住宅安裝太陽能板。此舉創美國首例,並可能為太陽能業帶來巨大的推動力。
加州是美國最昂貴的地區之一,即便此規定估計會提高新房的前期成本近一萬美元,這項決策仍獲加州能源委員會五位委員一致通過,是加州因應全球氣候變化所做的另一努力。
據加州能源委員會估計,這項新標準將增加每月房貸約四十美元,但會被每月為住戶所節省的八十美元能源費所抵銷。
「我們不能讓加州人住在那些基本上等於住宅版耗油車的房子裡」,能源委員會主席大衛‧霍克希德在投票前說。
新的建築規範包括建築通風和照明標準的更新。加州官員表示,新的建築規範預計在三年內要將加州的溫室氣體排放量總共減少七十萬公噸,這相當於減少十一‧五萬輛汽車的排放量。
這次投票是太陽能安裝業的一大勝利,太陽能業已將加州視為最大市場。能源委員會在今年稍早的一項研究中預測,新標準可能會使加州對太陽能設備的需求提高百分之十至十五。
加州所進行的是美國最具雄心的再生能源計畫之一,目標是在二○三○年前,將該州一半的電力需求改由再生能源供應。據能源委員會統計,二○一七年底,加州的再生能源供電比例已達約百分之三十。
這樣的政策,使得加州這美國人口最多的一州,與政策急轉彎、撤回對抗氣候變化政策的川普總統常有扞格。加州州長傑瑞‧布朗計劃在今年九月舉行全球氣候峰會。
據能源委員會引述二○一七年美國能源部的報告指出,在有三千九百五十萬人口的加州,目前僅有百分之九的獨棟房屋住戶裝有太陽能電池板。
加州能源委員會發言人安珀‧貝克說,若建築物被陰影遮蔽,或屋頂太小,裝不下太陽能面板,則可以免受此規範限制。

The strongest earthquake to hit Taiwan in 25 years killed at least 16 people and damaged dozens of buildings, but the destruction was largely contained thanks to decades of preparedness work. Taiwan sits on the “Ring of Fire,” an arc of intense seismic activity along the Pacific Rim, and — much like neighboring Japan — has a long history of catastrophic quakes. How does April 3 compare with other recent quakes? The April 3 earthquake, which measured 7.4 on the moment magnitude scale, was felt across Taiwan. It was the most severe since a 7.6 magnitude quake in 1999 killed
Around the time of the Dragon Boat Festival in June, the streets of Taiwan are filled with the delightful aroma of zongzi, a traditional snack made of sticky rice wrapped in leaves. The leaves are folded into a cone and then filled with sticky rice and other ingredients such as braised pork belly, peanuts and salted duck egg yolks. The filled leaves are then tightly tied with kitchen twine and ready for cooking. 每到六月端午時節,街頭巷尾就會飄出粽子的香氣。粽子是將糯米包進粽葉的傳統美食,先將粽葉折成圓錐狀塞入糯米,以及紅燒肉、花生、鹹鴨蛋黃等配料,用棉線綁緊後即可烹煮。 Dragon Boat Festival (n. phr.) 端午節 aroma
Everyone has seen a piece of fruit turn brown after being cut. Have you ever wondered why that happens? It is a common phenomenon that occurs due to a chemical reaction called enzymatic browning. The appearance, flavor and nutritional value of the fruit are all affected by this reaction. Some fruits, such as apples, pears, bananas, avocados and peaches, are more prone to enzymatic browning than others. These fruits contain high levels of an enzyme called polyphenol oxidase, or PPO for short. __1__ This causes a chain of chemical reactions that ultimately transforms the phenolic compounds into
There are several methods to prevent or slow down enzymatic browning in fruit. __3__ This lowers the pH level of the fruit tissue, causing the PPO to be far less active. Another method is to store the fruit in an airtight container or to wrap it tightly with plastic wrap. Doing this will reduce its exposure to oxygen. __4__ Although fruit that has undergone enzymatic browning may look less appealing, it is still safe to eat. However, by using one of these simple methods, you can enjoy fresh-looking fruit for a longer period. 有一些方法能避免或減緩水果的酶促褐變。其中一個有效的方式就是在切片水果的表面塗上酸性物質,像是檸檬汁或醋。這樣做能降低水果組織的酸鹼值,讓 PPO 更不為活躍。另一個方式是將水果存放在密封的容器內,或用保鮮膜將其緊緊包住。這樣做會減少水果與氧氣的接觸。快速蒸一下切片水果或將其短暫浸泡在滾水中也能使PPO失去活性,並終止 PPO 與空氣的作用。 雖然經歷酶促褐變的水果可能看起來較不吸引人,但仍然可以安全食用。然而,藉由採用這些簡單方法中的其中一個,你就能在更長的一段時間享用看起來新鮮的水果。 What Did You
