UNIT 6: THE GREEN ENVIRONMENT - Exercise 1 ⇱
Circle the correct option to indicate the correct option that best fits each of the following numbered blanks from 18 to 22
Solar power is all about harnessing the energy of the sun by using solar panels to convert sunlight into usable electricity. This highly efficient form of energy produces zero emissions, ___(1)___. Moreover, solar panels are perfect for installation on a small scale, such as in private homes, since they require very little maintenance and have a long lifespan. However, the ability to generate solar power depends on the time of day and weather conditions. This means that solar panels are often less helpful ___(2)___.
Wind power, on the other hand, ___(3)___ using large turbines. Wind power doesn't produce any greenhouse gases, but it is not ideal for private use since turbines require consistent care. However, wind farms can be installed on a large scale and ___(4)___. This means that if there were more investments in wind power, it could be a viable way to provide energy for major cities and even for whole regions.
Wind and solar power contribute significantly to a green environment by reducing our reliance on fossil fuels, ___(5)___. Additionally, using renewable energy sources helps promote spending on sustainable development by creating new career opportunities in the green energy sector.
For now, the biggest challenge of adopting green energy is the costs associated with installation and infrastructure, but the benefits unquestionably outweigh the downsides.

___(6)___. These shortages have raised electricity prices and forced many families into poverty. The shortages came about because of increased demand after the global pandemic and some military conflicts.
During the COVID-19 pandemic in 2020-2021, energy demands dropped and production declined. After the pandemic, the energy suppliers failed to meet the renewed demand. After that, some military conflicts caused serious troubles in delivering fossil fuels like oil and gas, which means that ___(7)___.
The fuel crisis has led to a food crisis ___(8)___. Energy is needed for food production, and as fuel prices increase, so do food production costs. In other words, food prices have increased worldwide, leading to a cost-of-living crisis in many countries.
Another adverse effect of the energy crisis is that people have gone back to using coal and wood as fuel sources. ___(9)___.
We should consider using electricity from renewable sources rather than oil and gas. These clean renewable sources, such as solar, wind, hydropower, geothermal, tidal, and biomass, ___(10)___. Reducing our reliance on fossil fuels can end the energy crisis, reduce pollution, and slow climate change.
