麻煩科技英文高手幫我訂正一下文法是否正確

Since the industrial revolution during the eighteenth century, the fossil energy currently provides the main source of energy supplying the global. With the fossil energy source gradually depleted, price of crude on the rise. Thus, people pay more and more attention on renewable energy and green energy, for example, solar energy, wind energy, water energy and biomass, etc… Currently, the solar energy was believed to be possessed the developed potential and application value for the one of renewable energy. But, there are still some drawbacks as follow: the install cost of solar panels is high, and the conversion efficiency is still lower. Thus, the solar system usually uses the DC-DC converter for improved regulation capability.

    Since the industrial revolution in the eighteenth century, the fossil energy has provided the main source of energy to the world. With the fossil energy sources gradually depleted, and price of crude oil on the rise, people are paying more and more attention on renewable energy and green energy, such as, solar energy, wind energy, water energy and biomass, etc… Currently, the solar energy is one of renewable energy believed to have good potential and marketable value. However, there are still some drawbacks such as -- the installation cost of solar panels is high, and the conversion efficiency is still relatively low. Therefore, the solar system usually uses the DC-DC converter for improved regulation capability.

    Therefore, the solar system usually uses the DC-DC converter for improved regulation capability. --- This is not true at all. I am an electrical engineer. Solar panel systems use DC to AC inverters so that it can power the appliances in homes, or even step up to connect to electrical utilties.

    小型,孤立系統或須裝置蓄電池時, 用 DC-DC

    Yes, you can store it in the batteries using DC, you still need an inverter to get it to AC so that your appliances and light bulbs can be powered in the home ..

    As for efficiency, stepping it up to 120vac or 220vac is certainly more efficient than 24vdc, 36vdc batteries

    for example, solar energy, wind energy, water energy and biomass, etc該處不須改成 solar cell system ,因為那一句是說明能源類型.

    Currently, the solar energy was believed 這裡要改為solar cell system.

    因為後續的dc-dc converter 一般是配合solar cell 使用.

    至於converter 是AC or DC?

    看系統用途而定.

    小型,孤立系統或須裝置蓄電池時, 用 DC-DC.

    大型系統可能用DC-AC 較多.

    Since the industrial revolution happened during the eighteenth century, the fossil energycurrently has provided the main source of energy supplying to the global.( have + pp………since S +Ved 表示 “自從何時,就已經……..”) With the fossil energy source is gradually depleted, the price of crude oil is on the rise. Thus, people pay more and more attentions on renewable energies and green energies, for example, solar energy, wind energy, water energy and biomass etc., Currently, the solar energy was believed to be possessed (應使用主動式)the development potential and application value for the as one of renewable energies. But still, there are still some drawbacks as follow: the installation costs of solar panels is are high, and the conversion efficiency is still comparatively lower. Thus, the solar system usually uses the DC-DC converter for to improved its regular capability.
