Course language is Hebrew! English subtitles are planned but not yet available. The Hebrew course description will be followed by an English one. השימוש בדלק לסוגיו הוא התשתית שעליה מבוססים החיים המודרניים. כבר יותר ממאה שנה אנו משתמשים בדלקים מאובנים שנאצרו בבטן האדמה – נפט, גז טבעי ופחם – כדי להניע את גלגלי עולמנו: תעשייה מתקדמת, תחבורה מהירה, בתים נוחים ועוד. בקורס זה ננסה לבחון אלטרנטיבות אפשריות לדלקים המאובנים, הגורמים נזק לא מבוטל לסביבתנו ולבריאותנו. נתאר את המחקר המדעי האינטנסיבי המתקיים בתחום, ונציג מגוון טכנולוגיות מתקדמות להפקת אנרגיה נקייה ממקורות טבעיים ומתחדשים – כמו השמש, הרוח והמים – מקורות המצויים בשפע, אינם מזהמים, ואינם מתכלים. קורס המבוא לאנרגיה מתחדשת ייפתח בשאלות הבסיס של תחום האנרגיה: מהם צורכי האנרגיה של האנושות כיום, ואילו משאבים עומדים לרשותה? אילו תהליכים אנו מכירים לאיסוף, המרה וניצול של מקורות אנרגיה? מהן הבעיות שנוצרות עקב השימוש הנוכחי במקורות אנרגיה מאובנים? ואיזה שינוי נדרש במדיניות האנרגיה ובמשק האנרגיה של החברה המודרנית? מכאן נעבור לתיאור הסוגים העיקריים של אנרגיה מתחדשת – מקורות אנרגיה טבעיים, זמינים ובלתי מתכלים, שאינם גורמים נזק סביבתי, ועשויים להחליף את הדלקים המאובנים. נדבר על אנרגיית השמש, אנרגיית הרוח, אנרגיית המים וביו-אנרגיה; ננתח את הטכנולוגיות הקיימות כבר היום לניצול המקורות הללו לצורכי האדם; נציג כלים בסיסיים לחישוב יעילות ההמרה של כל טכנולוגיה, וכמויות האנרגיה שניתן להפיק באמצעותה; ונביא דרכים להערכת הכדאיות הכלכלית של כל אחת מהשיטות. במקביל, נדון בקשיים ובאתגרים הממתינים עדיין לפתרון, ונשאל מה יש לעשות כדי שהאנרגיות המתחדשות ייושמו בקנה מידה רחב – בתעשייה, בתחבורה, ובכל תחומי חיינו. נבחן מגוון טכנולוגיות מתקדמות להפקת אנרגיה ממקורות נקיים; נסביר מדוע הן עדיין אינן תופסות את מקומם של הדלקים המאובנים; ונציג כיווני מחקר עכשוויים ופיתוחים חדשניים שמשפרים ומייעלים לא הרף את השיטות הקיימות, במטרה להבטיח לכולנו עתיד בר-קיימא. הקורס כולל חישובים כמותיים ורצוי מאד רקע בפיסיקה ומתמטיקה ברמה של תיכון. על מנת לצבור קרדיט אקדמי של אוניברסיטת תל אביב עבור הקורס, יש לעמוד בהצלחה בבחינה שמתקיימת באוניברסיטת תל אביב. תוכלו למצוא מידע נוסף בקישור הבא - https://tauonline.tau.ac.il/registration. בנוסף, ניתן להתקבל לחלק ממסלולי הלימוד באוניברסיטת תל אביב באמצעות הקורסים המקוונים. קראו עוד כאן -https://go.tau.ac.il/b.a/mooc-acceptance. מורים המעוניינים ללמד את הקורסים בכיתותיהם מוזמנים לקרוא כאן על תוכנית תיכון אקדמי מקוון - https://tauonline.tau.ac.il/online-highschool Course language is Hebrew! English subtitles are planned but not yet available. Fuels are the foundations of modern living. For over a century we have been drawing fossil fuels – oil, coal and natural gas – from the depths of the earth, and using them to power our world: advanced industries, fast transportation, comfortable homes and more. In this course we will examine possible alternatives for these fuels - which have proved quite damaging to both our health and our environment. We will describe the intensive worldwide efforts in this field of research, and present their encouraging outcome: a range of innovative technologies for generating clean energy from natural, non-polluting and renewable sources – such as sunlight, wind and water. The course will open with some fundamental questions on energy: What are the energy needs of the global population today, and what will they be tomorrow? What are the resources at our disposal? What are the known processes for harvesting, converting and utilizing resources of energy? What are the problems generated by the use of fossil fuels? In what ways must we change our energy policies and energy economy? And most important of all: What are the alternatives to fossil fuels, and can they supply humanity's extensive and constantly growing energy needs? Subsequent lessons will introduce the main types of safe, clean, natural and renewable energy sources available to us: solar energy, wind energy, water energy and bioenergy. We will speak of existing technologies that already harness these resources to the needs of humankind, and supply simple tools for computing conversion efficiencies, calculating the amounts of energy produced through the various methods, and assessing their economic feasibility. In parallel, we will discuss the remaining problems and challenges, and ask what must be done to enable the large-scale use of renewable energy – in industry, in transportation, and in every other sphere of our lives. We will examine several advanced renewable energy technologies; explain why they have not yet taken the place of fossil fuels; and present cutting-edge innovations and promising research directions – in the ongoing global effort to ensure a sustainable future for us all. A background in physics and mathematics at high school level is highly recommended.
