By combining major renewable energy sources with technology, companies can help reduce greenhouse gas emissions, promote green energy, and fight climate change.
FREMONT, CA: Organisations around the world are increasingly recognising the urgency of moving to renewable energy to secure the planet’s well-being. Adopting and implementing solutions to attain sustainable, clean, and affordable energy sources is vital in reducing greenhouse gas emissions, promoting green energy, and fighting climate change.
There are some major renewable energy sources, when combined with technology, help in achieving these very goals.

Solar Energy
Solar energy technologies, such as concentrated solar power (CSP), photovoltaic (PV) systems, and solar thermal cooling and heating systems, absorb sunlight to generate thermal energy or electricity. PV systems convert sunlight into electricity directly, which enables them to offer a consistent and abundant energy source with reduced operating costs. These systems are scalable, which makes them befitting for commercial, residential, and utility-scale applications. On the other hand, the efficiency of PV systems is cut short by weather conditions, geographic location, the fluctuating nature of sunlight, and other factors.
Solar thermal heating and cooling systems directly make use of sunlight and convert it into energy used for space heating or cooling, hot water, and also for reducing reliance on conventional energy sources.
Wind Energy
Technologies in wind energy consist of onshore, offshore, and floating wind turbines. Onshore wind turbines are a cost-effective, mature technology that has the capability to generate electricity with reduced environmental impact. Offshore wind turbines provide higher and more consistent wind speeds, which results in a higher amount of energy production. Floating wind turbines are an up-and-coming technology which can be installed in deep waters as it taps into vast wind resources.
Hydropower
This type of technology consists of large-scale hydroelectric power plants, pumped hydroelectric storage, and small-scale hydropower. Large-scale hydropower plants generate electricity by using the gravitational force of flowing water to their advantage. It offers a reliable, low-cost source of electricity with reduced greenhouse gas emissions.
Small-scale hydropower systems have lower environmental and social impacts, which makes them a more sustainable alternative.
Pumped hydro energy storage use excess electricity to pump water uphill and stores energy as gravitational potential energy. When the demand for electricity increases, the water is released downhill to generate electricity.
Geothermal Energy
Technologies for geothermal energy include geothermal power plants and ground-source heat pumps, and they use Earth’s natural heat to create energy. Geothermal power plants create electricity by using underground reservoirs of steam or hot water. These plants provide a stable and continuous supply of electricity, with reduced greenhouse gas emissions. Ground-source heat pumps make use of Earth’s stable temperature to provide cooling and heating for buildings. These systems are designed to be energy efficient and therefore help significantly reduce dependency on conventional energy sources.
