A definitive guide to solar energy and its advantages and drawbacks

The modern world is characterized by an overwhelming population explosion and a consequent tussle for natural resources. The fast-depleting natural resources supply poses a serious threat to future generations, causing a dire need for sustainable alternatives. Solar energy is among the most commonly utilized alternative fuel sources today and is being utilized in homes and offices at small-scale and large-scale levels. This article discusses how solar energy works, its advantages and drawbacks, and its functions:

How does solar energy work?
Extraction of solar cells : Solar energy is powered by panels made of solar or photovoltaic cells, generated by blending melted crystalline silicon with gallium or boron. Each silicon ingot or “wafer” thus formed comprises a positively charged and a negatively charged silicon layer.

Manufacturing of solar panels : These solar cells are used to manufacture large, black solar panels. The silicon semiconductors in these panels absorb sunlight to generate electricity.

Electricity generation : The positively and negatively charged silicon layers in the ingots in solar cells form an electric field in the panel. When the panels absorb sunlight, the electrons in the ingots separate from the atoms. The electrical field around each wafer sets these electrons in motion, generating direct current (DC), which is converted to alternating current (AC) and utilized in homes and offices.

Electricity utilization : The AC electricity passes the electric panel and powers your home. The regular electricity supply can compensate for any shortage of solar energy.

Advantages of solar energy
Natural resource conservation : Solar energy is a renewable source facilitating natural resource conservation, contributing to a sustainable future.

Environment-friendly alternative : Solar power plants do not cause air pollution or emit greenhouse gasses, which is a significant step towards a healthier environment.

“Native” energy source : Solar energy is referred to as a “native” energy source, as it is available across the planet and generates local employment.

Reduction in energy bills : Replacing traditional electric power with solar energy can reduce your energy bills. Moreover, you can avail of credit for unutilized surplus energy.

Unaffected by power outages : Solar energy can continue functioning even during power outages.

Disadvantages of solar energy
Space utilization : Solar panels occupy space on rooftops and open areas. Thus, thorough planning and space allocation is required before solar panel installation.

Suitable only for permanent residences : Another major disadvantage is that solar panel systems are not portable. Thus, individuals frequently changing homes cannot reap the benefits of solar energy.

Expensive project : Installing solar panels can be time-consuming and expensive, particularly at a large-scale level. Considerable financial planning is required before undertaking the project.

Better suited to sunny weather : Although solar energy can be harnessed in areas receiving perennially less sunlight, the supply of solar energy may be very less, requiring support from traditional electricity sources.

While installing solar panels can be cumbersome and time-consuming, it can be highly rewarding, personally and environmentally. Proper planning and coordination with reputed solar panel installers can help you eliminate the cons of installation and enjoy its benefits.

12 surprising facts about COPD to know

12 surprising facts about COPD to know

Chronic Obstructive Pulmonary Disease, also known as COPD, is a well-recognized respiratory ailment that affects millions of lives worldwide. COPD, characterized by symptoms like chronic cough, shortness of breath, and reduced lung function, is a complex condition with multiple layers. While its core features are understood by many, an array of surprising and often overlooked facets surrounds this condition. This article delves into these lesser-known aspects of COPD to comprehensively understand the disease. Underdiagnosed and misdiagnosed cases One of the most surprising facts about COPD is the prevalence of underdiagnosed and misdiagnosed cases. According to the World Health Organization (WHO), more than 90% of COPD cases are estimated to remain undiagnosed. This is partly because early symptoms, such as coughing and shortness of breath, are often attributed to the natural aging process or other respiratory conditions. Additionally, many individuals with COPD do not seek attention until the disease has progressed significantly. Impact on mental health COPD not only affects physical health but also takes a toll on mental well-being. Surprisingly, individuals with COPD are more likely to experience anxiety and depression. The disease’s chronic nature and its impact on daily activities and social interactions may lead to isolation and sadness.

7 lesser-known signs of multiple myeloma

7 lesser-known signs of multiple myeloma

Multiple myeloma is a type of cancer that primarily affects the plasma cells found in the bone marrow. Plasma cells typically produce antibodies to help the body fight infections. However, in multiple myeloma, certain plasma cells become cancerous and start to multiply uncontrollably, crowding out healthy blood-forming cells in the bone marrow. These cancerous plasma cells can produce abnormal proteins, which can accumulate in the blood and urine, leading to various health problems. Here are the lesser-known signs of multiple myeloma: Recurrent infections Multiple myeloma weakens the immune system, making individuals more susceptible to infections. However, this sign is often overlooked or attributed to other causes. Recurring or persistent infections, such as respiratory infections, urinary tract infections, or skin infections, can be an early indication of an underlying immune system dysfunction caused by multiple myeloma. The connection between multiple myeloma and infections lies in the disease’s impact on plasma cells’ production of antibodies. As the cancerous plasma cells multiply in the bone marrow, they crowd out healthy cells responsible for producing antibodies, impairing the body’s ability to fight infections effectively. Recognizing the link between recurring infections and multiple myeloma can lead to earlier diagnosis and treatment, which may improve the patient’s overall prognosis.
