These fluctuations impact on the Earth producing geometric storms which cause possible satellite failure, possible power grid failure, communication difficulties and unusual auroras. Example of the Sun's sunspot activity causing power grid failure is that of 1989, where a geomagnetic storm caused one of the transformers in the power transmission grid of hydro Quebec in Canada to fail. This event precipitated the collapse of the entire power grid. Despite this, the sun also contributes positively to such technologies such as solar panels.
In conclusion the Sun affects the Earth life, the environment and technology in both positive and negative ways. However, life would not exist without the sun to power it.
