地熱エネルギーと温泉


火山活動はしばしば破壊をもたらしますが、地熱や温泉を生みだすなど有益にもなり得ます。


蒸気から得られる地熱

地熱発電を行うには、地下から漏れ出す高圧の蒸気を使って発電機に繋げられたタービンを回転させます。地熱発電は従来の発電方法より二酸化炭素の排出量が少ないため、地熱は環境にやさしいエネルギー源です。


温泉

温泉は、地熱によって摂氏25度以上に熱された地下水と定義されています。温泉はしばしば豊富なミネラルと天然ガスを含んでいます。この地域にある多数の火山のおかげで、十和田八幡平国立公園は豊富な温泉保養地を有しています。


Geothermal Energy and Hot Springs


Volcanic activity is often destructive, but it can have benefits, including creating geothermal energy and hot springs.


Geothermal Energy from Steam

To generate geothermal electric power, highly pressurized steam escaping from below the Earth’s surface is used to turn turbines connected to electricity generators. As this produces lower levels of carbon dioxide emissions than conventional power generation methods, it is an environmentally friendly energy source.


Hot Springs

An onsen hot spring is defined as groundwater heated by geothermal heat to more than 25°C. Such springs often contain an abundance of minerals and natural gases. Thanks to the large number of volcanoes in the region, this national park has a wealth of hot spring resorts.
