"All energy is ultimately derived for the sun and harvesting it directly through solar power seems to be the best way to transition to renewable energy.", PETER RIVE Solar energy is heat and light from the Sun used by a range of modern techniques and devices. These devices include solar thermal energy, solar heating, photovoltaics, molten salt power plants, solar building, and artificial photosynthesis. Solar energy works by catching the Sun's heat and converting it into electricity for your home or business. The Sun is a natural atomic reactor. It issues tiny packets of energy called "photons", which cover the 93 million miles from the Sun to Earth in about 8.5 minutes. Every hour, sufficient photons strike our planet to produce enough solar energy to meet global energy needs for a whole year. Currently, photovoltaic power is not used much worldwide. But solar technology is developing, and the cost of going solar decreases; so, our capacity to use the Sun's energy is on the rise.
Uses of solar energy products:
The use of solar energy is increasing each and every day. Now solar energy products are being used not only for commercial purposes but also for domestic purposes. People are using more and more solar energy products. Following are top examples of using solar energy: Solar-powered transportation: One of the best ways to efficiently use the sunshine is with transportation powered by photovoltaic (PV) energy. Subways, railroads, cars, buses, planes, and even roads can all be powered by solar. Solar transportation is becoming a famous contribution to the renewable energy sector. The solar-powered-aircraft Solar Impulse 2 made its way around the world, flying across the Pacific and making huge sprinkles in iconic photographs. Meantime, solar buses are supporting China to reduce its carbon footprint while having efficient mass transit in huge-populated cities like Beijing. Finally, solar cars are beginning to play a role in racing sports worldwide, especially in Australia, where the SolarSpirit model has attained significant recognition. Wearable solar tech: Powering the electronics has become a typical solar power use nowadays. Solar-powered chargers can charge anything from a cell phone to an e-reader or tablet. There are also solar-powered flashlights that are charged by being exposed to sunlight. Down below are top tech in solar products:
- Cell phones
- Music speakers
- Solar dryers
- Solar visor radios
- Rechargeable flashlights
- Solar air conditioning
Solar lighting: These include solar lights, lamps, garden lights, etc. Solar lights can work using sunlight during the day time. Extra solar energy can be stored in batteries for use in evenings and nights. Solar lamps may work for 5-10 hours a day, depending on the LED Light size, size of the battery, etc. Solar Lights are a simple way to reduce electricity bills and give alternatives to the harmful effects of kerosene lights in villages. The solar lights/ lamps are very useful in villages without electricity connection. In modern-day cities too, these lamps are also handy, especially during power blackouts. Solar heating: Many homeowners don't know that solar water heaters and solar space heaters efficiently heat their homes without making the larger investment of installing solar panels. Solar space heaters use sunlight and change it into thermal energy using air or liquid as a medium, while solar water heaters use water as a means for heat transfer. These solar heating systems can be active or passive. Passive systems use natural flow. Active systems use pumps to flow water and produce heat. A significant benefit of solar thermal technology is the capability to heat your pool at a cheaper rate than standard options such as oil and gas pumps. At its simplest, the technology utilizes a solar receiver that harnesses sunlight and turns it into heat. Water is then moved through the receiver as a means of heating the pool. You can use this technology to make the water cooler in the water. Solar heating systems range between $3,000 and $4,000 and give a payback time as short as one and a half years. Rooftop solar: There are so many amazing gadgets and instruments available under the Sun. It's easy to miss the most important solar energy use: rooftop solar. While solar energy can be used to charge a battery and fly an aircraft, you can use it to save money every year by cutting carbon footprints, utility bills, and energy use.
Benefits of using solar energy to the environment:
Solar Energy is a clean, budget-friendly, and sustainable way to produce electricity. Along with actual financial benefits, solar power has significant environmental advantages as well. Reduces our reliance on fossil fuels: Solar energy generation does not need fossil fuels and is, therefore, less reliant on this limited and valuable natural resource. Fossil fuels have finite resources and may vanish one day; renewable energy sources are unlimited in availability. Reduces air pollution: Fossil fuels emit harmful carbon dioxide and methane gas into the air. They are the principal contributors to global warming and reduced air quality. Producing electricity with solar panels, however, provides no greenhouse gasses whatsoever and thus decreases air pollution. Reduces water wastage: Solar energy doesn't contaminate local water sources because solar photovoltaic cells don't need water to produce power. On the other hand, fossil fuels use water for nearly every phase of their electricity production. Helps fight climate change: Solar energy decreases the climate change dangers risks. These risks arise while generating power using fossil fuels. Combusting fossil fuels to produce electricity has led to the severe warning of global warming and constant climate change. Solar power is now competing with other sources of energy without releasing the dangerous greenhouse gases that cause climate change. Helps reduce our household's carbon footprint: A domestic solar panel system can provide electricity demands of a complete home with about 80% lower carbon eruptions than fossil fuels. Installing a domestic solar panel system will decrease your home's utility bill while remarkably reducing its annual carbon footprint at the same time.
Top 5 solar nations:
Let's have a look at the top 5 countries using solar power: 1. Germany: Total use: 10,000 megawatts Germany is the top leading country in solar energy and aims to be 100% renewable by 2050. In 2018 alone, Germany installed 6,301 megawatts of solar energy capacity, which is more than Spain's total capacity and about eight times more than the US recently installed. 2. Spain: Total use: 3500 megawatts Spain was at the top in newly-installed PV solar energy (2,605 MW) in 2016, but Germany overtook as its newly-installed capacity decreased remarkably (to just 69 MW) in 2017. This drop is attached to the suspension and complexity of a new government grant program and a reduction in energy demand due to the economic disaster. With expectations that both will change, Spain will bump up its solar power capacity again next year. 3. Japan: Total use: 2700 megawatts A surprise entry at No3, Japan has set a big solar energy goal of reaching 28 GW by 2022 and 53 GW by 2030. They spent nearly $9 billion in their solar energy program last year alone, and the government also declared a plan to install solar power at 32,000 schools. 4. United States: Total use: 1800 megawatts From a comparatively-low starting point, solar energy use is expected to overgrow in the US over the next few years, due to many solar projects in the pipeline. These were supported not only by supportive state-level policies but also by raising the Federal solar tax credit cap in 2018. 5. Italy: Total use: 1300 megawatts In 2018, Italy had experienced the second-largest solar energy growth worldwide. They have installed more solar power systems in recent years and are planning to increase numbers in upcoming years.
