Fuentes de energía – Clip

The video explains how biofuels are derived from plants that capture energy from the Sun. These plants can be processed to extract alcohol, which serves as fuel for vehicles. After harvesting, the plants are replanted to ensure a continuous supply of this renewable energy source. However, the growth of biofuels takes longer than their consumption, necessitating a balance between growth and usage to maintain sustainability.

What is the initial product extracted from biofuels for use in vehicles?

• Methane

• Hydrogen

• Ethanol

• Biodiesel

What is the process called when biofuels are replanted after harvesting?

• Recycling

• Regeneration

• Replanting

• Reforestation

What term is used to describe plants that are used as fuel?

• Biofuels

• Fossil fuels

• Solar fuels

• Wind fuels

Why is it challenging to use biofuels as a renewable energy source?

• They require a lot of water

• They take longer to grow than to harvest

• They are expensive to produce

• They are not environmentally friendly

What must be done to ensure biofuels are an effective renewable energy source?

• Grow more than we use

• Use more than we grow

• Grow as much as we use

• Stop using them altogether
