Every summer, the number of Australian homes equipped with air conditioners goes up and up. Recent statistics show that 74% of Australian homes – 6.6 million so far – have some form of air conditioning. This stands to reason because our summers are becoming hotter and hotter while we increasingly demand constant comfort.
At the same time, air conditioners drive up electricity demand, straining the electricity network. So what are you to do if you want to enjoy a guilt-free, full night’s sleep?
Many solar energy projects in Africa fail because they lack proper planning and long-term government support, according to a study on solar power in Nigeria. The study, published last month in Renewable Energy, sought to find out why solar power is failing to deliver cheap energy to people in Nigeria. The researchers found that governments and agencies planning solar projects lacked awareness of how many people they wanted to reach, whether the location of planned solar parks was suitable and how the plant and the households it would benefit would be connected to the grid.
Energy remains one of the main constraints for economic growth in Nigeria. The lack of reliable access and irregular power supply is a persistent problem affecting businesses across the country. It also discourages foreign investors. Nigeria sits at the bottom of the table when it comes to delivering power. It ranks 187 out of 189 countries in the world, according to a World Bank business report. The current output of renewable energy as a percentage of the overall energy mix in the country is very low. The energy mix is largely dominated by oil which makes up 57% and natural gas 36%. Solar power and hydropower represent 13% and 7%, respectively.
Not only was December 2015 the UK’s wettest month on record, but it was also exceptionally stormy. Bad news for many, but great news for the country’s wind power and hydro generators.
In fact, storms Desmond, Eva and Frank meant that throughout December, more than 19% of Great Britain’s (not the UK’s – as Northern Ireland is not included in the underlying data) electrical energy came from wind, solar and hydro combined. That’s the highest ever figure for a calendar month.
