Should more be done to introduce renewable energy as the main source?

It is no secret that fossil fuels are both running out, and having a negative impact on the environment. We have the knowledge and equipment to translate natural energy into power, a process which has a far less, if not no negative effect on the environment and therefore there should be a greater global push to bring renewable energy to the forefront. We have wind turbines across the UK which are a great use of generating energy, and solar panels are on the rise appearing on fields up and down the country. The next big breakthrough appears to be tidal energy, with scientists and researchers coming up with the best and safest way to generate energy from existing crashing waves in our oceans. There's been a shift in society in recent years to champion renewable energy to protect the universe, but we just aren't there yet. There needs to be a greater push globally to make renewable energy the only energy we use as soon as possible.
