Examine the information above relating to energy consumption in Ireland by fuel source in 1990 and in 2015 and answer each of the following questions - Leaving Cert Geography - Question A - 2017

In 2015, the percentage of energy consumed that was generated from coal dropped to 16.9%. This represents a substantial decrease, highlighting a shift towards alternative energy sources as part of efforts to reduce carbon emissions and promote sustainability.

Fossil fuels are natural substances formed from the decomposed remains of ancient plants and animals, subjected to heat and pressure over millions of years. This category includes coal, oil, and natural gas, which are primarily used for energy production and transportation.

In 1990, 95.1% of energy consumption was generated from fossil fuels. This percentage indicates that the majority of energy sources during that time were derived from fossil fuels, emphasizing the dependence on these non-renewable resources.

Renewable energy refers to energy generated from natural resources that are replenished continuously, such as sunlight, wind, rain, tides, waves, and geothermal heat. These sources are sustainable and produce little to no greenhouse gas emissions, making them environmentally friendly alternatives to fossil fuels.

One reason for the increase in the use of wind as an energy source is the growing awareness of climate change and the need for cleaner energy alternatives. Technological advancements have also improved the efficiency and cost-effectiveness of wind turbines, making wind energy a viable and attractive option for energy production.
