Experts agree that something needs to be done to help our environment. It’s under threat on all sides from, among other things, deforestation, global warming, CO2 emissions and intensive farming. The time for action has arrived, and governments, businesses and individuals all have a collective responsibility to ensure our world remains a viable place in which to live for future generations.
The concentrated removal of large quantities of the Amazon rainforest has led to dramatic increases in CO2 levels in recent years. The trees absorb many gases, keeping their effects in check, but without them the imbalance causes major problems throughout the world. It’s just one of many crucial battles against the erosion of our natural resources.
The use of fossil fuels has become a sensitive environmental issue, and concerns about their dwindling stocks have led to urgent research and development of alternative sources of energy. Heavy investment by governments and large corporations in recent years underlines the importance of finding another way to power our cars, homes and factories.
Many of the world’s motor manufacturers have been developing hybrid vehicles, which will run partly or solely on electricity. They’re obviously going to be playing a large part in the future of road transport, and it’s not hard to imagine an increasing number of filling stations that will include a recharging point somewhere among the petrol pumps in years to come.
However, it must be pointed out that if cars are to be running off the national grid, then we need to continue to find ways of developing a viable network of renewable energy. It’s all very well using less oil from the world’s reserves to power vehicles, but if the electricity is being generated by the continued use of fossil fuels, the net gains to the environment will be minimal.
Wind power is becoming a significant factor in the battle to save the planet. It’s clean, efficient and exceedingly cheap to run. Of course, windmills have been a distinctive, and very visible, means of harnessing energy from Mother Nature for many centuries. Industrial wind turbines are becoming equally familiar nowadays, with large installations dotting skylines all over the world.
Many people are using the same principles – albeit on a lesser scale – to generate electricity for the home. Smaller turbines have become a fixture on many houses in the last few years, and they look set to become even more widely used. They’re installed on a mast or directly onto the roof, and in no time they’re providing power for the homes at significantly cheaper rates than the energy suppliers can offer.
Equally green, and perhaps better known, is solar energy. Drawing power from the rays of the sun isn’t difficult, thanks to the advances in technology in the last few years. Photovoltaic panels collect energy from the sky, even on a cloudy day, which can then be used to heat water and run electrical appliances with ease.
