A biofuel is stuff made from plants or animal waste that you can burn, or otherwise use, to get heat or power. It can be a liquid, like plant alcohol for cars, a gas from rotting plant matter, or even solid stuff like wood pellets.

A biofuel Biofuel is是 stuff made from plants or animal waste用植物或動物廢棄物做成的東西 that you can burn, or otherwise use你可以拿來燃燒或用其他方式使用 to get heat or power來取得熱或動力。It can be可以是 a liquid液體, like plant alcohol for cars像是給汽車用的植物酒精, a gas from rotting plant matter或是植物腐爛產生的氣體, or even solid stuff like wood pellets甚至是像木屑顆粒這樣的固體。

So it is the umbrella word: bioethanol and biogas are kinds of biofuel, and bioenergy is often the power you get when you use them. People talk about biofuel when they want energy that did not come from old oil under the ground.

So因此, it is the umbrella word它是一個統稱: bioethanol and biogas bioethanol 和 biogas are kinds of biofuel都是 biofuel 的一種, and bioenergy而 bioenergy is often通常是 the power you get when you use them用它們所得到的動力。People talk about biofuel人們談到 biofuel when they want energy that did not come from old oil under the ground是想要不是來自地底舊石油的能源時。

Though actually, “from plants” does not automatically mean “kind to the earth” — fields, water, and smoke still matter, and some biofuels are much cleaner in practice than others.

Though actually不過其實, “from plants”「來自植物」 does not automatically mean “kind to the earth”不代表自動就是「對地球友善」 — fields, water, and smoke still matter農地、用水和排放的煙還是有影響, and some biofuels are much cleaner in practice than others而且有些 biofuel 實際上比其他的乾淨得多。

You will see the word in news and school texts about energy. It is more formal than “plant fuel,” which nobody really says.

You will see the word你會在 in news and school texts about energy談能源的新聞和學校教材裡看到這個字。It is more formal than它比 “plant fuel,”「plant fuel」還正式, which nobody really says而幾乎沒有人真的這樣講。
