Read the following passage about powering the future and mark the letter A, B, C or D on youranswer sheet to indicate the option that best fits each of the numbered blanks from 31 to 40.

As we continue to face the impacts of climate change, having a green environment has becomeincreasingly important to the future of our society. To achieve this, the world is shifting towards greenenergy, and two particular types of energy at the centre of this movement are solar power and wind power.

[I] This highly efficient form of energy produces zero emissions, so it can significantly reduce ourcarbon footprint. [II] Moreover, solar panels are perfect for installation on a small scale, such as in privatehomes, since they require very little maintenance and have a long lifespan. [III] However, the ability togenerate solar power depends on the time of day and weather conditions. This means that solar panels areoften less useful if they are installed in places where sunny weather is not typical. [IV]

Wind power, on the other hand, involves converting the energy of the wind into electricity usinglarge turbines. Wind power doesn't produce any greenhouse gases, but it is not ideal for private use sinceturbines require consistent care. However, wind farms can be installed on a large scale and are able toproduce electricity continuously regardless of the time of day. This means that if there were moreinvestments in wind power, it could be a viable way to provide energy for major cities and even for wholeregions.

Wind and solar power contribute significantly to a green environment by reducing our reliance onfossil fuels, helping us cut down on pollution and slow climate change. Additionally, using renewable energysources helps promote spending on sustainable development by creating new career opportunities in thegreen energy sector.

For now, the biggest challenge of adopting green energy is the costs associated with installation andinfrastructure, but the benefits unquestionably outweigh the downsides. If we want to stop the climatecrisis and create a better and more sustainable future, green energy sources will undoubtedly be thekey.
